Inner Core

Solid iron ball around 5.000 degrees celcius

Outer core

This layer is made of nickel and Iron. Due to its high temperature the metals are liquid. Due the spinning of the earth the metals are spinning and moving like a ocean.

Mantle

It's divided in two parts

Upper mantle is attached to the crust and together they form the lithosphere. This is a fixed shell and this is broken up in tectonic plates.

Lower mantle

Here rock is no longer solid and moves up and down due to heating and cooling of the rock.

This layer pushes the layer above it.

Crust

A thin cool layer of rock that covers the entire earth. This is the section we live on.

Learning goals
