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.

What is magma called when it comes through the surface?

So why do the tectonic plates move?
And how can we see that

That was the lesson

Check for yourself if you understand all the learning goals

On the right you will see all the learning goals we discussed this chapter. Drag them to field you think it belongs.

No!

I don't understand this at all.

I still find this very hard

I am starting to understand

I think I understand this

YES!

I understand it completely 

You know that the earth consist of a core, a mantle and the Earth’s crust.

You understand how Wegener recognized that the earth’s crust consisted of different moving plates that once were adjoined

You understand how plates can move.

You know the earth’s crust consists of different plates.
