Structure Of The Earth Facts

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 that is the first layer the mantle the second layer the outer core the third layer the inner core the last layer.

Facts about each layer:

Crust - The crust is the shortest layer it is 40 km long it is solid brittle deepest hole in the world got up to 12 km they had to stop because it got to hot and the tools stop working.

Mantle - The mantle is the thickest layer, it is made out of melted rocks that makes it soft and squishy.

Outer Core - The outer core is so hot it gets to the temperature of the surface of the sun, this layer is total liquid.

Inner Core - Now the inner core is solid even though it is so hot because the pressure from all of the other layers of the Earth around it.

Our group - Buster/Me Cameron Tristan.

First we created a 3D image of the earth using ….. soft clay, knife.

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.
