Driving Question #1
How does the core allow life to survive on the surface? How would the earth be different if the core was a different size or temperature than it is now?
The heat given off as the core cools flows from the core to the mantle to Earth's crust through a process known as convection. Like a pan of water boiling on a stove, convection currents move warm mantle to the surface and send cool mantle back to the core. This escaping heat powers the geodynamo and coupled with the spinning of Earth generates the magnetic field. We could not live without this magnetic field. Without the magnetic field, we wouldn't be protected from space radiation.
The core is impoetant because it will make the layers to stay, and gravity is one of the important cases. If the core was bigger, we might have bigger earth or hotter earth on the surface. If it had high temperature, earth would be hot and if it was cold earth could be colder.
Earth' score allows us to survive here on the surface by rising the magnetic field that protects us from the harmful space radiation! If the core were a different size, the magnetism would either not be enough protection, or there would too much magnetism on this planet.
We know the structure of Earth's Interior from observing the behavior of seismic waves generated during earthquake activity. The main divisions are the: crust, mantle, outer core and inner core. The mantle is further subdivided into zones based on seismic wave activity, these zones being the: upper mantle, asthenosphere and the stiffer lower mantle. It is true that the outer core is a rotating fluid, the composition of which is most likely dense iron and nickel. The inner core is solid. Without it's ozone layer we won't be protected by the suns harmful rays
Well, as a matter of fact we know that core is the center of the gravity, and we know without gravity we would not stay on earth. Also layers of earth were not in order and all earth would made from same layers. If core was bigger or smaller then the gravity would change. If core was bigger we would be a bigger earth or we could have less layers on earth. If core was hotter I think all the earth was melt and I was no rocky layer.
Earths core does a lot for our planet. For example the earths core creates the magnetically field around our planet. If the core was smaller, or a different temperature, we would not have as strong of a magnetic field around our planet. If the core were to be lower in temperature, then the core would have a much higher viscosity, and this would effect the rocks we see on the surface
The magnetic field protects us for. The space radiation, which is very harmful. Convention currents move the warm mantle to the surface And sends the cool mantle back to the core. If the core was bigger, we might have a bigger earth or a hotter earth on its surface.
The core causes the magnetic field which to the presence of life on the surface. The majority of the magnetic field is generated here and the field helps shield the earth from solar radiation. The degree of harmful solar radiation would dictate life, so any change in the core would have an influence towards the life on earth.
The core is one of our main sources of energy which is stored in the center of the earth. The heat radiated to create tropical weather and so on. The closer we get to the equator the warmer it is and so when we get further away from the equator which is centered of earth it's known to be colder. I found out that the core rotates and so this might have an effect in how our earth has a consistent speed at which it orates and help create seasons. What was really interesting was when the proto earth radiated heat scientists wasn't sure where all that heat went to either outer space or somewhere.
We would not survive. There'd be no gravity to live with we'd have a less dense planet. And we'd be living possibly on a protoearth planet. Oh wait we wouldn't live we'd all DIE.
Earth's core plays a huge role because it creates a magnetic field around our planet. It protects us from the space radiation which can be very dangerous. Core's temperature helps the surface of the earth.
The core is very important because it protects us from solar radiation. It also is the cause of the magnetic field that protects us. Any change to the core would have an influence on earth.
The core is the main provider to our magnetic field that surrounds earth and that blocks any kind of harmful radiation from coming into our atmosphere and giving all of us radiation poisoning. So without our core we would pretty much not be able to live on earth. Also if our core was bigger then it would just block more of the radiation because it would cause our magnetic field to be bigger, but earth may be hotter and some water may evaporate because of how close the core is. If our core was smaller then we may have radiation let into our atmosphere and then our earth would be uninhabitable.
The surface is not affected by the core because of plate tectonics, they block out the heat from us. The plates are always moving though, so sometimes magma from the mantle seeps through and that is what comes out of volcanoes http://en.wikipedia.org/wiki/Earth Earths core is where all the gravity on earth is. We are all pulled towards the earth because of the core, so if the core were a different size it would have more or less gravity. We would either be weightless or we would be crushed into the ground. If the core was a different temperature, it would screw things up because at the temp it is right now, everything is like clock work. http://helios.gsfc.nasa.gov/qa_earth.html#earthcore
If earths core was and bigger it would offset our center of gravity that is holding everything together and we would not be here if the core was any bigger it would be to hot on the surf
Earth's core allows life to survive on the surface through temperature, pressure and creating a magnetic field that protects us from harmful radiation from the sun. The iron core is small enough that it's high temperature does not make it too hot on the surface to support life but it is also large enough to have enough of a gravitational pull that maintains the magnetic field surrounding the Earth. The temperature is also hot enough to keep the planet warm enough so that not everything freezes and cool enough so that everything does not melt.
the core makes the magnetosphere which protects us from the harmful radiation from the sun and without the core the sun would probably be hurt by the radiation it stops
1. Since the inner core is a solid metal ball, scientists believe it causes our Earth to be magnetic… with the outer core’s movement controlling the magnetic field. Dense metals, such as iron and nickel, sank to the center of the Earth to form the core. Because the dense materials sank down and compressed together, it allowed the lighter materials such as air and water to exist on the surface. The materials existing on the surface are what allow us to live.
When the earth was formed all of the heavier, more dense, substances drifted into the inner core, leaving the lighter, less hot materials to be towards the crust such as water and air. The crust acts as the insulator of the earth, and it will never be as hot as the mantle. The rocks in the inner crust will melt, but it is not hot enough to melt the crust itself. Also, the crust is much more thick than we originally think, because by size comparison it seems small to us. If the core was any bigger, or if it was any hotter, the crust would most likely melt into the earth and life would not be sustainable. If the core was any smaller, or colder, it would freeze up and once again would not be suitable for life forms, nor would the chemical composition stay the same.
1. The structure of Earth’s interior was observed from seismic waves activity. There are three zones based on the seismic wave activity being upper mantle, asthenosphere and the stiffer lower mantle. Earths core contributes to the magnetic field. The magnetic field helps protect earth from solar radiation and changes to this would cause issues towards life on earth.
Maintains magnetic field and space radiation.The earth's magnetic field is generated mainly at the core, as the highly conductive metallic fluid of the outer core rotates with respect to the solid inner core, generating electric currents and an accompanying magnetic field.
The deep inner-core of the Earth creates the magnetosphere that protects us from the harmful rays that the sun has i.e. the radiation. Without such a field all of life would be fried by charged particles. If the magnetic poles were to disappear, then most of life would vanish since we depend upon it to survive.
The inner core may be hotter, but it is at a much higher pressure. At a fixed temperature (say 5000 degrees), high pressure can make a liquid into a solid. The heat radiates to the Earths surface and it provides heat through out the surface. So, even though the temperature increases as you move into the inner core, the pressure increases faster and wins.
The inner core is mainly made up of different medals like iron and nickel, this is because these medals sank to the center of the earth to form the core. The core creates and maintains a magnetic field which helps protect earth from space radiation.

The size of our core produces a magnetic field around our world that protects against radiation and keeps the inhabitants of this world from dying from radiation. If the core was bigger than it is than the magnetic field would be greater and if it was hotter than that would only make the surface more hot and water would evaporate and cause a different climate to form.
The iron core maintains a magnetic field, which creates electric fields and protects us from the sun's radiation. If the core changed in any way, the magnetic field would be affected, which would lead to issues such as more radiation coming in from the sun.
The earths core allows us to survive because the core protects us from radiation that could poison us! Without the core we would all die. If the core was bigger then our magnetic field would be bigger but earth may get a lot hotter and water would evaporate because the core is too close. If the core was smaller then radiation would be able to get to us and it would be almost impossible to live on earth.
The core allows life to exist with its magneticism. The inner core provides the magnetic field while the outer core controls it. This magnetic field protects the planet from charged particles from other sources, like the sun. Without it, the planet would most likely not be able to support life. Another way life is supported is through the density of the objects. Because metal is denser than air, it positioned the corresponding elements in terms of their density, bringing the air and water up to the surface a d supporting life. The Earth would be different because of the different positioning of the magnetic fields. The change in size would cause more debris to collect on Earth, therefore making it bigger and more dense. It would change the physical features of the Earth and possibly make the whole planet warmer from the inside.
The earths core is very vital to us; it creates a magnetic fields that protects us from space radiation. Without this protection we could not survive. If anything about the core changed we could not survive
The core support life in earth because of convection. Cooler mantel goes down to the core and hotter rises to the surface. The earths spin also creates a magnetic field that protects us from radiation from outer space. If the core were different or bigger our temperatures would change or the earth would be bigger
The earths core is very important for several different reasons, one being that it is the center of gravity, which plays a really big role in our day to day life. Also the magnetic fields our core produces protects us from harmful radiation. Without this, there would be no chance for survival
The core has multiple purposes for allowing life to live on the surface. For one, the core is responsible for the magnetic field present on the earth, which is necessary because if we didn't have it, all life would be constantly fried by charged particles from the sun or cosmic rays. It also is the center of gravity, which is essential to our ability to inhabit the earth. If the core were any different, the force of the magnetic field would be altered, and plate tectonics would either move too fast or not at all, altering the geography of the earth.
The inner core spins, to protect the sun from its harmful rays. This is called the magnetic field. If the core was a different size or temperature than earth wouldn't be able to sustain life because the core would either be too hot or too cold.
The core has a very important purpose for allowing life to live on the surface because it is the center of gravity. The core also provides the magnetic field which protect us from harmful radiation. If the core was a different temperature we wouldn't be able to sustain life because it would be too cold or hot, and it were a different size the force of the magnetic field would different and couldn't protect us from the harmful radiation. Therefore if the core was any different we couldn't sustain life.
Earths core is responsible for the magnetic field which blocks radiation from coming in, which keeps us alive because if there was to much radiation then we would most likely get radiation poison and die eventually. The core is also the center of gravity which is key to be able to live on earth. If the core was a different size then our magnetic field would be different and could cause us to not be able to live on earth, it would also change the plate tectonics and would change the geography of earth.
The Earth core is responsible for the magnetic field of the Earth that shields the Earth from harmful outer space radiation. The Earth core is the right size for generating the right level of gravity that keeps the atmosphere of the Earth, including Oxygen of course which with out, life would have been impossible.
Earths core is the perfect size to create a large enough magnetic field around Earth to protect it from harmful radiation. This has allowed life to evolve on Earth due to the right level of gravity generated by the magnetic field to keep to atmosphere on Earth. If the core was a different size it may not be able to hold enough gravity to keep an atmosphere on the planet.
The inner core of the Earth is solid metal that spins which creates the magnetic field around Earth. The field protects the Earth from most of the sun's harmful rays such as radiation. Because we are protects by the magnetic field life was able to form without the threat of the sun's harmful rays.
The core is the main component to the magnetic field around the earth that keeps us on the ground(gravity) and also protects us from harmful radiation. If the core was bigger it could be one, to big causing gravitation to be too strong for life and secondly be to hot for life on the surface of the earth.
The core of the Earth, made of iron and nickel, rotates, which creates a magnetic field. This large magnetic field acts as a sort of shield from solar radiation. The solar radiation, if left unshielded, would strip away the atmosphere and boil the oceans. A similar event is believed to have happened on Mars, leaving it the cold, lifeless rock it is today.
If the core was smaller, like the core of Mars, it would cool much more quickly and leave the surface without a magnetic field. If it were cooler, the same process would occur.
The core of the Earth is what gives the planet it's magnetic field, and protects us from radiation. If it was of a different size, the outcome would be different. Too big and it'll be too hot, too small and there would not be enough magnetism for the magnetic field, exposing us to radiation.
Earth's core allows life on the surface because of a process called convection. The core creates a magnetic field blocking out all space radiation. If the core were smaller and at a lower temperature then there would not be a strong magnetic field on the surface and it would strip away the atmosphere.
The core allows life to sustain on the surface because the core is the main source of energy and life so it makes everything around it work and remain intact. The Cambrian explosion is what initially set up the beginning of the core being the main source of energy. If the core were to change in any way then the Earth could lose several aspects like its magnetic field for example, and the earth would be different than it is now.
Our core allows us to live on this planet by supplying us with the basic elements necessary to human life. If the core was smaller or burned at a lesser temperature human life wouldn't be able to survive on this planet.
If the core was any smaller, it would be less dense, so the pull of gravity would be weaker. The moon might spiral away from us faster, or we might fly right into the sun. If the core was bigger, the opposite would occur, making Earth more dense. The moon might be pulled back into Earth and make it even MORE dense. Any change would drastically effect the magnetic field that protects us from the suns radiation.
The earth's core is made out of liquid nickel on the outside and the inner core is made out of solid iron. The fact that our core is revolving gives us a magnetic field. It protects us from harmful radiation from the sun and space.
The earths metallic core is very important for it creates the magnetic field that surrounds the earths surface and protects life on the planet from deadly radiation which would slowly give all life radiation poisoning if it were not there. The metal core is also very important for it is what we call the center of gravity and is what keeps us from floating off into space and if it were any bigger or smaller it would change the force of gravity that we experience. If the core was any different temperature life would not be able to exist on this planet.
The magnetic field is concentrated in the core of the Earth, which protects us from harmful radiation. The core is also a certain size and temperature that allows life to be possible. If the core were any colder or hotter life wouldn’t be possible. If the size were any different, the magnetic field would not be able to protect us from radiation.
The metal core of our earth provides an invisible ring of protection around our earth that protects the earth's surface from the sun's rays. Mars doesn't have a metal core that protects it's surface and it is a dry and hot planet. Mars does, though, show signs of once having oceans on it. Scientists believe that Mars once had a metal core, but because of the small size of the planet and core, it eventually ran out of energy and stopped providing a ring of protection from the suns rays. Gradually the oceans evaporated and mars became the dry and hot planet it is today. Mars is a great example of the protection our metal core provides us. If our core were smaller, it would provide a smaller and weaker ring of protection. Therefore the suns rays would have a larger effect on our surface and atmosphere causing our earth to become drier and hotter.
1. With today’s technology, we are able to use seismological and magnetic field data to get a possible calculation of the size and composition of the interior Earth. The Earth’s core is made of iron and in some places is 10,000 degrees Fahrenheit. The heat of the core is due to the slow decay of radioactive elements left over from when the planet first formed. The molten iron outer core is about 3000 kilometers below the surface, and the solid iron inner core is another 2000 kilometers further down. This core prevents the planet from being harmed by the Sun’s radioactive rays allowing life to survive on the surface. If the inner earth were cold, there would be no volcanoes, but also no uplift of land or subduction and recycling of ocean sediments. Eventually all of the mountains and islands would erode and be deposited on the seafloor, making the Earth all water, and not satisfying life on Earth.
The inner core saves us from dangerous radiation and keeps living things on earth safe from them. If the core was bigger it would make the radiation "shield" bigger but it would also make the surface of earth hotter cause water to evaporate easier.
due to the magnetic field that the earth has it helps to keep to the heat that is produced by the core convection. and that magnetic field pulls magnetic matern to the core
The earth's core supplies us with a magnetic field that acts as a shield against the harmful radiation. The absence of this magnetic field in planets would cause Earth to be inhabitable, especially by humans. If the core was bigger then earth would be too hot and our water would evaporate at a much higher pace. If it was smaller then the radiation would be overpowering and life would not be able to survive on Earth.
Our planet was created for life. A smaller planet, like Mars, would be unable to hold our atmosphere, which protects us from meteoroids and keeps the temperature within the range needed for life.
A larger planet, like Neptune, would trap too much atmosphere. The pressure and temperature would greatly increase. A stronger gravity from the increased size would also trap harmful gases in the atmosphere.
Earth has a strong magnetic field. This protects us from harmful radiation from the sun.
Geological change has been a constant occurrence on our planet since the time of its formation and the first appearance of life. The Earth formed about 4.5 billion years ago from accretion from a solar nebula which resulted in volcanic encasing of our atmosphere. There was not any oxygen and it was not a suitable place to incase life. Over time our planet cooled and formed a solid crust and inner core. Since the core is a solid hot ball it radiates heat to the upper layers, resulting in convection currents and causing movement of tectonic plates. The inner core is responsible for creating a magnetic field and radiation, which keeps the planet warm. Changing the size and temperature of both o the inner core would result in human inability to endure life on Earth.
Due to the mixture of iron and nickel in the earth's core, a magnetic field is able to form which protects humans and other life on earth. This protects us from harmful cosmic rays from space.The tempreture of earth core greatly effects tempreture of earth on the surface as well as magnetic polar shifts.
The core allows the Earth to support life by maintaining a certain temperature, so that the Earth is neither too cold nor too hot for life to survive. If the core were smaller in size the earth would likely be a frozen wasteland, too cold for many life to survive, and conversely if the core were a hotter temperature. The core also does other key things that allow life to survive, such as the movement of the plates and the core itself.
The iron core of the Earth creates a magnetic sphere around the Earth that helps protect the surface from solar winds. The iron core also protects the Earth from harmful amounts of utlraviolet rays. UV rays are still able to penetrate the Earth but it at a much less severe rate than if the iron core did not exist. The flow of liquid in the core also allows for the wind patterns and atmospheric conditions to exist as they do. If the atmospheric conditions differed from what they are today, the Earth would be a much different place. It would, ultimately, lack the ability to support life. If the core were to cool down and become solid iron, the magnetic field that encompasses the Earth would be destroyed. This would be detrimental to the health of our planet and it's ability to support life. The atmosphere would be subjected to severe solar winds and this could cause the atmosphere to be completely stripped away leaving the Earth at the mercy of relentless and vicious space.
The solid center and the liquid outer part of the core protect the eath from solar radiation that our sun gives off! Differences in temperature and composition in the two core regions drive this powerful and protective electromagnetic field.
The core of the earth creates a magnetic field that protects the surface of the earth from harmful radiation. This magnetic field is created by the mixture of iron and nickel in the core. If the core was larger then it would create a larger and more protective magnetic field but also change the surface temperature at the earth's surface in a negative way.
The core is very important because for ones it creates the magnetic field around our earth. And without our magnetic field we can be harmed from space radiation! If the core somehow dropped in temperature, it could affect many things that we see on earth for example loss of oxygen.
The flow of the metallic liquid in Earth's core creates our magnetic field that protects us from solar storms and other objects. Without it, there would be no hope of advanced species on Earth. If the Earths core wasn't the temperature that it is, it wouldn't be hot enough to turn the metal into liquid, hence the magnetic field would not be here.
The core's heat creates a magnetic field that protects us from radiation. The warm mantle is moved to the surface and the cool mantle is moved back to the core through Convention Currents. The size of the core is what the size of our earth is based on. The core helps our planet to maintain the temperature that it needs to be so we can still survive. Our core is the perfect size because if it was any smaller, human life would not be able to survive.
The core produces a magnetic field around us that protects against radiation and keeps us alive. If the core was larger than the magnetic field would be greater, which would cause the climate to change.
The core is important because it creates a magnetic field around the earth which protects us from space radiation. It also provides the earth with heat and minerals.
Earth's solid-metal inner core is important to the planet, helping to give rise to the magnetic field that protects us from dangerous radiation, but its distance from the planet's surface means that there is much we don't know about what goes on down there. The movement of the liquid outer core results in the dynamo that causes the Earth's magnetic field. But some things about of the inner core are being revealed by acoustic waves passing through the planet's heart and iron squeezed to large pressures. Many earthquakes are caused by those acoustic waves in the core of Earth.
The core reacts with the liquid magma layer creating a magnetic field. This magnetic field is very important to our survivor. Without it there is pretty much a zero percent chance that we would not be able to survive on this earth. It also contributes to our gravity and rotation, which if it were any different there could be a possibility of us not living.
The inner core of the earth is made of solid iron and mickle. The inner core is almost 4,000 miles from the surface of the earth. There are many other levels between thersurface and the inner core so when the earth was formed all the heavy and hot elements sunk into the inner core but through the many layers of rocks and magma the lighter element like water and air make up the surface because they are not as hot.. The crust is the insulator of the earth, it keeps the heat towards the inner core. If the core was any stronger or hotter, the crust would most likely be too hot for life to be sustainable. If the core was weaker or colder, it would freeze up and once again would not be suitable for us to live on it. Like mars which is too hot and Jupiter is too cold.
The core allows life on the surface of the earth because the ore's heat creates a magnetic field around the earth that protects us from radiation and other harmful rays.The earth would be different if the core was different because there may not be volcanoes or mountains, or even bodies of water.The current size and temperature of the core maintains earth at a temperature that we need to survive.
Primarily the core allows us to live on the surface because it generates a magnetic field that shields us from a harmful amount of solar radiation. If the core was any bigger it would make the planet too hot to live on, like Venus. If it was smaller it wouldn't have a large enough gravitational pull to maintain the electromagnetic field, and the solar radiation would kill us.

The earths inner core is very important to the earth. It creates the magnetic field that protect the earth from harmful radiation. If it were a different size or temperature, the earths magnetic field would be completely different.

The core of the earth creates a magnetic field that protects the earth from radiation and if the size or heat of the core changed it would alter that magnetic field and the heat of our planet.
The core of our earth is helping us big time in creating that magnetic field so radiation isn't hurting us. Iron & nickel create the magnetic force from the core. If the core was larger the surface of earth would be much hotter, but the magnetic field would also be larger.
The Earth has a solid inner core distinct from its liquid outer core. The core is a huge source of energy. Warmer weather is possibly created from the cores heat. The closer we get to the center of the earth (equator) the warmer it is and visa-versa. In the mantle of the earth is underneath the crust and if there is any movement there it may cause tectonic activity such as volcanic eruptions and earthquakes. The core is located beneath the mantle and is the hottest deepest layer of earth, which is made of mostly metal. The core consist of two layers. The outer core and the inner core. The outer core is somewhere between 4000 and 5000 degrees Celsius. The inner core is mostly iron. It is between 5000 and 7000 degrees Celsius. The pressure from the rest of the planet is so great that the iron cannot melt. This is why the inner core is solid. The entire planet is magnetic because of the ball of metal in the middle. It is believed the outer layer controls the earths magnetic field. It protects the planet from charged particles in the solar system.
Our core causes are entire planet to be magnetic. This magnetic field acts as a bubble protecting us from charged particles and radiation. It also help to control the north and south poles. If the temperature were any different the planet would not be able to sustain life. It would either be too hot or too cold like other planets in our solar system.

The earth's core creates a magnetic field around our planet. If the core was smaller, or a different temperature, we would not have as strong of a magnetic field around our planet and this wouldn't keep us safe from radiation. If the core were to be lower in temperature, then the core would have a thicker substance, and this would effect rocks we see.
Our core creates a large magnetic field that protects us from solar wind. If it was smaller then the field wouldn't be as strong or even non-existent. If it were a different temperature, the Earths surface would be too different for sustaining life.
Earth's core allows life to survive by creating a magnetic field to protect Earth from harmful radiation. If the core were any different, we wouldn't be able to live on Earth. This is because the magnetic field that the core generates would either be too much or too little. Any change would affect our magnetic field.
\outl0\strokewidth0 \strokec2 The core is made up of iron metal ball which is like a magnet.The magnetic Field is protecting the life on the planet from solar particle.\ If the core is not solid the size of earth would be smaller and volcanoes and earthquakes will not exist.
The core is very important for several reasons, one of which is the fact that it is the center of gravity. Also, the core is a solid core, made up of iron which acts as a magnet. This is where the magnetic waves are produced that protect us from the harmful radiation. The larger the core, the hotter the surface.
Our core is very important, our core causes the entire planet to be magnetic. This magnetic field act like a bubble, protecting us from radiation and charged particles. One thing it also helps control is our north and south poles. Without it, our temperature as a planet would either be very cold, or too hot for earth to be about to sustain life.
The Earths iron core raises the magnetic field which protects us from the sun's rays and allows life to form. If it was bigger, earth would be bigger or smaller and there would be either not enough of a magnetic field or too much, which would either give us not enough protection from the sun's rays or too much and not allow enough sun light. This is how it works.
The core is the center of gravity and is also a solid core. It causes the whole planet to be a magnetic field so it can protect earth from harmful radiation.
If the core of Earth were to be slightly smaller or larger our magnetic field would be all out of sync and may not exist at all meaning we would have no protection from charged particles floating around the solar system such as those from the sun.
The earths core has many heavy metals which creates a magnetic field which stops many solar flares from entering earths atmosphere. The core is so dense that it keeps the atmosphere from being sucked up into space
The Earth's core creates the magnetic field that protects us from solar flares. Also, if the core was different, life on the surface would be unpredictable and chaotic. All of the movement below the surface would stop.

Well, as a matter of fact we know that core is the center of the gravity, and we know without gravity we would not stay on earth. Also layers of earth were not in order and all earth would made from same layers. If core was bigger or smaller then the gravity would change. If core was bigger we would be a bigger earth or we could have less layers on earth. If core was hotter I think all the earth was melt and I was no rocky layer.
ReplyDeleteEarths core does a lot for our planet. For example the earths core creates the magnetically field around our planet. If the core was smaller, or a different temperature, we would not have as strong of a magnetic field around our planet. If the core were to be lower in temperature, then the core would have a much higher viscosity, and this would effect the rocks we see on the surface
ReplyDeleteThe magnetic field protects us for. The space radiation, which is very harmful. Convention currents move the warm mantle to the surface And sends the cool mantle back to the core. If the core was bigger, we might have a bigger earth or a hotter earth on its surface.

ReplyDeleteThe core causes the magnetic field which to the presence of life on the surface. The majority of the magnetic field is generated here and the field helps shield the earth from solar radiation. The degree of harmful solar radiation would dictate life, so any change in the core would have an influence towards the life on earth.
ReplyDeleteThe core is one of our main sources of energy which is stored in the center of the earth. The heat radiated to create tropical weather and so on. The closer we get to the equator the warmer it is and so when we get further away from the equator which is centered of earth it's known to be colder. I found out that the core rotates and so this might have an effect in how our earth has a consistent speed at which it orates and help create seasons. What was really interesting was when the proto earth radiated heat scientists wasn't sure where all that heat went to either outer space or somewhere.
ReplyDeleteWe would not survive. There'd be no gravity to live with we'd have a less dense planet. And we'd be living possibly on a protoearth planet. Oh wait we wouldn't live we'd all DIE.
ReplyDeleteEarth's core plays a huge role because it creates a magnetic field around our planet. It protects us from the space radiation which can be very dangerous. Core's temperature helps the surface of the earth.
ReplyDeleteThe core is very important because it protects us from solar radiation. It also is the cause of the magnetic field that protects us. Any change to the core would have an influence on earth.
ReplyDeleteThe core is the main provider to our magnetic field that surrounds earth and that blocks any kind of harmful radiation from coming into our atmosphere and giving all of us radiation poisoning. So without our core we would pretty much not be able to live on earth. Also if our core was bigger then it would just block more of the radiation because it would cause our magnetic field to be bigger, but earth may be hotter and some water may evaporate because of how close the core is. If our core was smaller then we may have radiation let into our atmosphere and then our earth would be uninhabitable.
ReplyDeleteThe surface is not affected by the core because of plate tectonics, they block out the heat from us. The plates are always moving though, so sometimes magma from the mantle seeps through and that is what comes out of volcanoes
ReplyDeletehttp://en.wikipedia.org/wiki/Earth
Earths core is where all the gravity on earth is. We are all pulled towards the earth because of the core, so if the core were a different size it would have more or less gravity. We would either be weightless or we would be crushed into the ground. If the core was a different temperature, it would screw things up because at the temp it is right now, everything is like clock work.

If earths core was and bigger it would offset our center of gravity that is holding everything together and we would not be here if the core was any bigger it would be to hot on the surf
ReplyDeleteEarth's core allows life to survive on the surface through temperature, pressure and creating a magnetic field that protects us from harmful radiation from the sun. The iron core is small enough that it's high temperature does not make it too hot on the surface to support life but it is also large enough to have enough of a gravitational pull that maintains the magnetic field surrounding the Earth. The temperature is also hot enough to keep the planet warm enough so that not everything freezes and cool enough so that everything does not melt.
ReplyDeletethe core makes the magnetosphere which protects us from the harmful radiation from the sun and without the core the sun would probably be hurt by the radiation it stops
ReplyDelete1. Since the inner core is a solid metal ball, scientists believe it causes our Earth to be magnetic… with the outer core’s movement controlling the magnetic field. Dense metals, such as iron and nickel, sank to the center of the Earth to form the core. Because the dense materials sank down and compressed together, it allowed the lighter materials such as air and water to exist on the surface. The materials existing on the surface are what allow us to live.
ReplyDeleteWhen the earth was formed all of the heavier, more dense, substances drifted into the inner core, leaving the lighter, less hot materials to be towards the crust such as water and air. The crust acts as the insulator of the earth, and it will never be as hot as the mantle. The rocks in the inner crust will melt, but it is not hot enough to melt the crust itself. Also, the crust is much more thick than we originally think, because by size comparison it seems small to us. If the core was any bigger, or if it was any hotter, the crust would most likely melt into the earth and life would not be sustainable. If the core was any smaller, or colder, it would freeze up and once again would not be suitable for life forms, nor would the chemical composition stay the same.
ReplyDelete1. The structure of Earth’s interior was observed from seismic waves activity. There are three zones based on the seismic wave activity being upper mantle, asthenosphere and the stiffer lower mantle. Earths core contributes to the magnetic field. The magnetic field helps protect earth from solar radiation and changes to this would cause issues towards life on earth.
ReplyDeleteMaintains magnetic field and space radiation.The earth's magnetic field is generated mainly at the core, as the highly conductive metallic fluid of the outer core rotates with respect to the solid inner core, generating electric currents and an accompanying magnetic field.
ReplyDeleteThe deep inner-core of the Earth creates the magnetosphere that protects us from the harmful rays that the sun has i.e. the radiation. Without such a field all of life would be fried by charged particles. If the magnetic poles were to disappear, then most of life would vanish since we depend upon it to survive.

ReplyDeleteThe inner core may be hotter, but it is at a much higher pressure. At a fixed temperature (say 5000 degrees), high pressure can make a liquid into a solid. The heat radiates to the Earths surface and it provides heat through out the surface. So, even though the temperature increases as you move into the inner core, the pressure increases faster and wins.
ReplyDeleteThe inner core is mainly made up of different medals like iron and nickel, this is because these medals sank to the center of the earth to form the core. The core creates and maintains a magnetic field which helps protect earth from space radiation.

ReplyDeleteThe size of our core produces a magnetic field around our world that protects against radiation and keeps the inhabitants of this world from dying from radiation. If the core was bigger than it is than the magnetic field would be greater and if it was hotter than that would only make the surface more hot and water would evaporate and cause a different climate to form.
ReplyDeleteThe iron core maintains a magnetic field, which creates electric fields and protects us from the sun's radiation. If the core changed in any way, the magnetic field would be affected, which would lead to issues such as more radiation coming in from the sun.
ReplyDeleteThe earths core allows us to survive because the core protects us from radiation that could poison us! Without the core we would all die. If the core was bigger then our magnetic field would be bigger but earth may get a lot hotter and water would evaporate because the core is too close. If the core was smaller then radiation would be able to get to us and it would be almost impossible to live on earth.
ReplyDeleteThe core allows life to exist with its magneticism. The inner core provides the magnetic field while the outer core controls it. This magnetic field protects the planet from charged particles from other sources, like the sun. Without it, the planet would most likely not be able to support life. Another way life is supported is through the density of the objects. Because metal is denser than air, it positioned the corresponding elements in terms of their density, bringing the air and water up to the surface a d supporting life. The Earth would be different because of the different positioning of the magnetic fields. The change in size would cause more debris to collect on Earth, therefore making it bigger and more dense. It would change the physical features of the Earth and possibly make the whole planet warmer from the inside.
ReplyDeleteThe earths core is very vital to us; it creates a magnetic fields that protects us from space radiation. Without this protection we could not survive. If anything about the core changed we could not survive
ReplyDeleteThe core support life in earth because of convection. Cooler mantel goes down to the core and hotter rises to the surface. The earths spin also creates a magnetic field that protects us from radiation from outer space. If the core were different or bigger our temperatures would change or the earth would be bigger
ReplyDeleteThe earths core is very important for several different reasons, one being that it is the center of gravity, which plays a really big role in our day to day life. Also the magnetic fields our core produces protects us from harmful radiation. Without this, there would be no chance for survival
ReplyDeleteThe core has multiple purposes for allowing life to live on the surface. For one, the core is responsible for the magnetic field present on the earth, which is necessary because if we didn't have it, all life would be constantly fried by charged particles from the sun or cosmic rays. It also is the center of gravity, which is essential to our ability to inhabit the earth. If the core were any different, the force of the magnetic field would be altered, and plate tectonics would either move too fast or not at all, altering the geography of the earth.
ReplyDeleteThe inner core spins, to protect the sun from its harmful rays. This is called the magnetic field. If the core was a different size or temperature than earth wouldn't be able to sustain life because the core would either be too hot or too cold.

The core also provides the magnetic field which protect us from harmful radiation. If the core was a different temperature we wouldn't be able to sustain life because it would be too cold or hot, and it were a different size the force of the magnetic field would different and couldn't protect us from the harmful radiation. Therefore if the core was any different we couldn't sustain life.
ReplyDeleteEarths core is responsible for the magnetic field which blocks radiation from coming in, which keeps us alive because if there was to much radiation then we would most likely get radiation poison and die eventually. The core is also the center of gravity which is key to be able to live on earth. If the core was a different size then our magnetic field would be different and could cause us to not be able to live on earth, it would also change the plate tectonics and would change the geography of earth.
ReplyDeleteThe Earth core is responsible for the magnetic field of the Earth that shields the Earth from harmful outer space radiation. The Earth core is the right size for generating the right level of gravity that keeps the atmosphere of the Earth, including Oxygen of course which with out, life would have been impossible.
ReplyDeleteEarths core is the perfect size to create a large enough magnetic field around Earth to protect it from harmful radiation. This has allowed life to evolve on Earth due to the right level of gravity generated by the magnetic field to keep to atmosphere on Earth. If the core was a different size it may not be able to hold enough gravity to keep an atmosphere on the planet.
ReplyDeleteThe inner core of the Earth is solid metal that spins which creates the magnetic field around Earth. The field protects the Earth from most of the sun's harmful rays such as radiation. Because we are protects by the magnetic field life was able to form without the threat of the sun's harmful rays.
ReplyDeleteThe core is the main component to the magnetic field around the earth that keeps us on the ground(gravity) and also protects us from harmful radiation. If the core was bigger it could be one, to big causing gravitation to be too strong for life and secondly be to hot for life on the surface of the earth.
ReplyDeleteThe core of the Earth, made of iron and nickel, rotates, which creates a magnetic field. This large magnetic field acts as a sort of shield from solar radiation. The solar radiation, if left unshielded, would strip away the atmosphere and boil the oceans. A similar event is believed to have happened on Mars, leaving it the cold, lifeless rock it is today.
ReplyDeleteIf the core was smaller, like the core of Mars, it would cool much more quickly and leave the surface without a magnetic field. If it were cooler, the same process would occur.
The core of the Earth is what gives the planet it's magnetic field, and protects us from radiation. If it was of a different size, the outcome would be different. Too big and it'll be too hot, too small and there would not be enough magnetism for the magnetic field, exposing us to radiation.
ReplyDeleteEarth's core allows life on the surface because of a process called convection. The core creates a magnetic field blocking out all space radiation. If the core were smaller and at a lower temperature then there would not be a strong magnetic field on the surface and it would strip away the atmosphere.
ReplyDeleteThe core allows life to sustain on the surface because the core is the main source of energy and life so it makes everything around it work and remain intact. The Cambrian explosion is what initially set up the beginning of the core being the main source of energy. If the core were to change in any way then the Earth could lose several aspects like its magnetic field for example, and the earth would be different than it is now.
ReplyDeleteOur core allows us to live on this planet by supplying us with the basic elements necessary to human life. If the core was smaller or burned at a lesser temperature human life wouldn't be able to survive on this planet.
ReplyDeleteIf the core was any smaller, it would be less dense, so the pull of gravity would be weaker. The moon might spiral away from us faster, or we might fly right into the sun. If the core was bigger, the opposite would occur, making Earth more dense. The moon might be pulled back into Earth and make it even MORE dense. Any change would drastically effect the magnetic field that protects us from the suns radiation.
ReplyDeleteThe earth's core is made out of liquid nickel on the outside and the inner core is made out of solid iron. The fact that our core is revolving gives us a magnetic field. It protects us from harmful radiation from the sun and space.
ReplyDeleteThe earths metallic core is very important for it creates the magnetic field that surrounds the earths surface and protects life on the planet from deadly radiation which would slowly give all life radiation poisoning if it were not there. The metal core is also very important for it is what we call the center of gravity and is what keeps us from floating off into space and if it were any bigger or smaller it would change the force of gravity that we experience. If the core was any different temperature life would not be able to exist on this planet.
ReplyDeleteThe magnetic field is concentrated in the core of the Earth, which protects us from harmful radiation. The core is also a certain size and temperature that allows life to be possible. If the core were any colder or hotter life wouldn’t be possible. If the size were any different, the magnetic field would not be able to protect us from radiation.
ReplyDeleteThe metal core of our earth provides an invisible ring of protection around our earth that protects the earth's surface from the sun's rays. Mars doesn't have a metal core that protects it's surface and it is a dry and hot planet. Mars does, though, show signs of once having oceans on it. Scientists believe that Mars once had a metal core, but because of the small size of the planet and core, it eventually ran out of energy and stopped providing a ring of protection from the suns rays. Gradually the oceans evaporated and mars became the dry and hot planet it is today. Mars is a great example of the protection our metal core provides us. If our core were smaller, it would provide a smaller and weaker ring of protection. Therefore the suns rays would have a larger effect on our surface and atmosphere causing our earth to become drier and hotter.
ReplyDelete1. With today’s technology, we are able to use seismological and magnetic field data to get a possible calculation of the size and composition of the interior Earth. The Earth’s core is made of iron and in some places is 10,000 degrees Fahrenheit. The heat of the core is due to the slow decay of radioactive elements left over from when the planet first formed. The molten iron outer core is about 3000 kilometers below the surface, and the solid iron inner core is another 2000 kilometers further down. This core prevents the planet from being harmed by the Sun’s radioactive rays allowing life to survive on the surface. If the inner earth were cold, there would be no volcanoes, but also no uplift of land or subduction and recycling of ocean sediments. Eventually all of the mountains and islands would erode and be deposited on the seafloor, making the Earth all water, and not satisfying life on Earth.
ReplyDeleteEarths core creates the magnetic field around our planet; any variation in size would affect our gravity, as well as climate
ReplyDeleteThe inner core saves us from dangerous radiation and keeps living things on earth safe from them. If the core was bigger it would make the radiation "shield" bigger but it would also make the surface of earth hotter cause water to evaporate easier.
ReplyDeletedue to the magnetic field that the earth has it helps to keep to the heat that is produced by the core convection. and that magnetic field pulls magnetic matern to the core
ReplyDeleteThe earth's core supplies us with a magnetic field that acts as a shield against the harmful radiation. The absence of this magnetic field in planets would cause Earth to be inhabitable, especially by humans. If the core was bigger then earth would be too hot and our water would evaporate at a much higher pace. If it was smaller then the radiation would be overpowering and life would not be able to survive on Earth.
ReplyDeleteOur planet was created for life.
ReplyDeleteA smaller planet, like Mars, would be unable to hold our atmosphere, which protects us from meteoroids and keeps the temperature within the range needed for life.
A larger planet, like Neptune, would trap too much atmosphere. The pressure and temperature would greatly increase. A stronger gravity from the increased size would also trap harmful gases in the atmosphere.
Earth has a strong magnetic field. This protects us from harmful radiation from the sun.
Geological change has been a constant occurrence on our planet since the time of its formation and the first appearance of life. The Earth formed about 4.5 billion years ago from accretion from a solar nebula which resulted in volcanic encasing of our atmosphere. There was not any oxygen and it was not a suitable place to incase life. Over time our planet cooled and formed a solid crust and inner core. Since the core is a solid hot ball it radiates heat to the upper layers, resulting in convection currents and causing movement of tectonic plates. The inner core is responsible for creating a magnetic field and radiation, which keeps the planet warm. Changing the size and temperature of both o the inner core would result in human inability to endure life on Earth.
ReplyDeleteDue to the mixture of iron and nickel in the earth's core, a magnetic field is able to form which protects humans and other life on earth. This protects us from harmful cosmic rays from space.The tempreture of earth core greatly effects tempreture of earth on the surface as well as magnetic polar shifts.
ReplyDeleteThe core allows the Earth to support life by maintaining a certain temperature, so that the Earth is neither too cold nor too hot for life to survive. If the core were smaller in size the earth would likely be a frozen wasteland, too cold for many life to survive, and conversely if the core were a hotter temperature. The core also does other key things that allow life to survive, such as the movement of the plates and the core itself.
ReplyDeleteThe iron core of the Earth creates a magnetic sphere around the Earth that helps protect the surface from solar winds. The iron core also protects the Earth from harmful amounts of utlraviolet rays. UV rays are still able to penetrate the Earth but it at a much less severe rate than if the iron core did not exist. The flow of liquid in the core also allows for the wind patterns and atmospheric conditions to exist as they do. If the atmospheric conditions differed from what they are today, the Earth would be a much different place. It would, ultimately, lack the ability to support life. If the core were to cool down and become solid iron, the magnetic field that encompasses the Earth would be destroyed. This would be detrimental to the health of our planet and it's ability to support life. The atmosphere would be subjected to severe solar winds and this could cause the atmosphere to be completely stripped away leaving the Earth at the mercy of relentless and vicious space.
ReplyDeleteThe solid center and the liquid outer part of the core protect the eath from solar radiation that our sun gives off! Differences in temperature and composition in the two core regions drive this powerful and protective electromagnetic field.
ReplyDeleteThe core of the earth creates a magnetic field that protects the surface of the earth from harmful radiation. This magnetic field is created by the mixture of iron and nickel in the core. If the core was larger then it would create a larger and more protective magnetic field but also change the surface temperature at the earth's surface in a negative way.
ReplyDeleteThe core is very important because for ones it creates the magnetic field around our earth. And without our magnetic field we can be harmed from space radiation! If the core somehow dropped in temperature, it could affect many things that we see on earth for example loss of oxygen.
ReplyDeleteThe flow of the metallic liquid in Earth's core creates our magnetic field that protects us from solar storms and other objects. Without it, there would be no hope of advanced species on Earth. If the Earths core wasn't the temperature that it is, it wouldn't be hot enough to turn the metal into liquid, hence the magnetic field would not be here.
ReplyDeleteThe core's heat creates a magnetic field that protects us from radiation. The warm mantle is moved to the surface and the cool mantle is moved back to the core through Convention Currents. The size of the core is what the size of our earth is based on. The core helps our planet to maintain the temperature that it needs to be so we can still survive. Our core is the perfect size because if it was any smaller, human life would not be able to survive.
ReplyDeleteThe core produces a magnetic field around us that protects against radiation and keeps us alive. If the core was larger than the magnetic field would be greater, which would cause the climate to change.
ReplyDeleteThe core is important because it creates a magnetic field around the earth which protects us from space radiation. It also provides the earth with heat and minerals.
ReplyDelete
ReplyDeleteEarth's solid-metal inner core is important to the planet, helping to give rise to the magnetic field that protects us from dangerous radiation, but its distance from the planet's surface means that there is much we don't know about what goes on down there. The movement of the liquid outer core results in the dynamo that causes the Earth's magnetic field. But some things about of the inner core are being revealed by acoustic waves passing through the planet's heart and iron squeezed to large pressures. Many earthquakes are caused by those acoustic waves in the core of Earth.
The core reacts with the liquid magma layer creating a magnetic field. This magnetic field is very important to our survivor. Without it there is pretty much a zero percent chance that we would not be able to survive on this earth. It also contributes to our gravity and rotation, which if it were any different there could be a possibility of us not living.
ReplyDeleteThe inner core of the earth is made of solid iron and mickle. The inner core is almost 4,000 miles from the surface of the earth. There are many other levels between thersurface and the inner core so when the earth was formed all the heavy and hot elements sunk into the inner core but through the many layers of rocks and magma the lighter element like water and air make up the surface because they are not as hot.. The crust is the insulator of the earth, it keeps the heat towards the inner core. If the core was any stronger or hotter, the crust would most likely be too hot for life to be sustainable. If the core was weaker or colder, it would freeze up and once again would not be suitable for us to live on it. Like mars which is too hot and Jupiter is too cold.
ReplyDeleteThe core allows life on the surface of the earth because the ore's heat creates a magnetic field around the earth that protects us from radiation and other harmful rays.The earth would be different if the core was different because there may not be volcanoes or mountains, or even bodies of water.The current size and temperature of the core maintains earth at a temperature that we need to survive.
ReplyDeletePrimarily the core allows us to live on the surface because it generates a magnetic field that shields us from a harmful amount of solar radiation. If the core was any bigger it would make the planet too hot to live on, like Venus. If it was smaller it wouldn't have a large enough gravitational pull to maintain the electromagnetic field, and the solar radiation would kill us.

ReplyDeleteThe core of our earth is helping us big time in creating that magnetic field so radiation isn't hurting us. Iron & nickel create the magnetic force from the core. If the core was larger the surface of earth would be much hotter, but the magnetic field would also be larger.

ReplyDeleteThe Earth has a solid inner core distinct from its liquid outer core. The core is a huge source of energy. Warmer weather is possibly created from the cores heat. The closer we get to the center of the earth (equator) the warmer it is and visa-versa. In the mantle of the earth is underneath the crust and if there is any movement there it may cause tectonic activity such as volcanic eruptions and earthquakes. The core is located beneath the mantle and is the hottest deepest layer of earth, which is made of mostly metal. The core consist of two layers. The outer core and the inner core. The outer core is somewhere between 4000 and 5000 degrees Celsius. The inner core is mostly iron. It is between 5000 and 7000 degrees Celsius. The pressure from the rest of the planet is so great that the iron cannot melt. This is why the inner core is solid. The entire planet is magnetic because of the ball of metal in the middle. It is believed the outer layer controls the earths magnetic field. It protects the planet from charged particles in the solar system.
ReplyDeleteOur core causes are entire planet to be magnetic. This magnetic field acts as a bubble protecting us from charged particles and radiation. It also help to control the north and south poles. If the temperature were any different the planet would not be able to sustain life. It would either be too hot or too cold like other planets in our solar system.

ReplyDeleteThe earth's core creates a magnetic field around our planet. If the core was smaller, or a different temperature, we would not have as strong of a magnetic field around our planet and this wouldn't keep us safe from radiation. If the core were to be lower in temperature, then the core would have a thicker substance, and this would effect rocks we see.
ReplyDeleteOur core creates a large magnetic field that protects us from solar wind. If it was smaller then the field wouldn't be as strong or even non-existent. If it were a different temperature, the Earths surface would be too different for sustaining life.
ReplyDeleteEarth's core allows life to survive by creating a magnetic field to protect Earth from harmful radiation. If the core were any different, we wouldn't be able to live on Earth. This is because the magnetic field that the core generates would either be too much or too little. Any change would affect our magnetic field.

ReplyDeleteIf the core is not solid the size of earth would be smaller and volcanoes and earthquakes will not exist.
The core is very important for several reasons, one of which is the fact that it is the center of gravity. Also, the core is a solid core, made up of iron which acts as a magnet. This is where the magnetic waves are produced that protect us from the harmful radiation. The larger the core, the hotter the surface.
ReplyDeleteOur core is very important, our core causes the entire planet to be magnetic. This magnetic field act like a bubble, protecting us from radiation and charged particles. One thing it also helps control is our north and south poles. Without it, our temperature as a planet would either be very cold, or too hot for earth to be about to sustain life.
ReplyDeleteThe Earths iron core raises the magnetic field which protects us from the sun's rays and allows life to form. If it was bigger, earth would be bigger or smaller and there would be either not enough of a magnetic field or too much, which would either give us not enough protection from the sun's rays or too much and not allow enough sun light. This is how it works.
ReplyDeleteThe core is the center of gravity and is also a solid core. It causes the whole planet to be a magnetic field so it can protect earth from harmful radiation.
ReplyDeleteIf the core of Earth were to be slightly smaller or larger our magnetic field would be all out of sync and may not exist at all meaning we would have no protection from charged particles floating around the solar system such as those from the sun.
ReplyDeleteThe earths core has many heavy metals which creates a magnetic field which stops many solar flares from entering earths atmosphere. The core is so dense that it keeps the atmosphere from being sucked up into space
ReplyDeleteThe Earth's core creates the magnetic field that protects us from solar flares. Also, if the core was different, life on the surface would be unpredictable and chaotic. All of the movement below the surface would stop.
