Structure of the Earth

Structure of the Earth Facts

We are learning about the structure of the Earth.

I learnt that the Earth is made up of 4 layers. They are the Crust, Mantle, Outer Core and Inner
Core,

Facts about each layer:

Crust - is the first layer of the Earth. It is between 8- 40kms thick and is made of Solid - Brittle
rock .

Mantle - is the second layer of the Earth and it is under the Crust. Also it is rocky and it is the
thickest layer. It is soft and squishy and hot.

Outer Core - is the third layer of the Earth and it is under the Mantle. Also it is very, very hot at
the Outer Core; it is 4000-6000.C and totally liquid.

Inner Core - is the fourth layer of the Earth and it is under the outer Core. It is also very, very
very, very hot down there. It is solid due to the pressure pushing down on it from the other layers
above.

Our group - Mollie, Sunita and Heidi.

First we created a 3D image of the earth using clay and paint.

We then cut the shape in half to show the different layers. After waiting for it to dry, we identified
each layer by painting them in different colours.

Below are some pictures of our work.
