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

– You know that the earth consists of a core, a mantle and the earth’s crust.

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

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

Why do people move next to volcanoes(sometimes active)

1. Like danger
2. Cheap to live
3. Fertile soil
4. No other place to live

Which statement is true

1. Oceanic plates are thinner and lighter
2. Oceanic plates are thinner and heavier
3. Continental plates are thicker and heavier

What the epicentre

1. The place in the earth's crust where the earthquake happens
2. The place on top of the earth's crust where the earthquake takes place

How does a tsunami occur?

Try to find the answer in your notes. I am going to ask someone to explain in 4 minutes

What are you going to do
