Hello there, we are looking for one answer. We are looking to find out why there is an inner core. thnx?

Question

This is for school and I need an answer asap why do we have an Inner Core, what is it used for, and what bearing does it hold on the earth and me?

Answer 1

that is where the "lake of fire" is
bad peeps will be thrown in there to die

Answer 2

Layers inside the earth consists of the inner core, outer core, mantle, and then the crust.

When earth first formed 4.5 billion years ago, it was a ball of molten rock. Because it was liquid, the heavier materials fell towards the center due to gravity. These heavier materials consisted of iron and nickel, and this is what the earth's core is made of. (outside of the core, the mantle, has cooled and become a putty like solid. It is made of less dense material than the core. Crust is the outer part of the mantle that has cooled completely and became hard).

The inner core is solid, I guess because of immence pressure, but the outer core is still hot liquid, and it is flowing. When you have metal spinning around like that, it creates a magnetic field. This magnetic field is important to us because it creates a magnetosphere around the earth that deflects charged particles that are streaming from the sun. If we didn't have the magnetosphere, living things will be irradiated by the solar particles, and the solar wind will also strip away the atmosphere.
There is a hypothesis that Mars once had a liquid core and had a magnetosphere. When the planet finally cooled and core became solid, the atmosphere was stripped away.

By the way, the liquid part is the outer core, not the inner core. I'm not sure if the inner core is spinnig as well (probably is, and this is only possible because the outer core is liquid) and if is also contributing to the magnetic field.

Answer 3

The layers of the earth include the crust, moho, mantle, outer core, inner core. The inner core is solid and dense, while the outer core is more of a fluid.
Earth's magnetic field is generated by the core, and is why you see the Aurora Borealis in the northern hemisphere, and the Aurora Australis in the southern hemisphere. This colorful display is caused by solar wind interacting with Earth's magnetic field. The magnetic field protects us from harmful radiation from the sun.

Answer 4

The inner core is the point of highest pressure with regards to the earth and gravity. Because of this pressure, the tectonic plates were created, on which our continents "float." There could never be no inner core, because were that so, the effect of gravity from the rest of the earth's mass would condense to fill its space.

Answer 5

One does not simply look great under flueroscent lights

Answer 6

refer to Ms k 's answer its all due to density of liquids, heavy trhings sink to the bottom lighter material to the top, simple!
