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. The top layer is the crust. The crust is the outermost layer of the Earth. It is made of solid rocks. The mantle  is  the thickest layer of Earth and it is like a gooey, oozing chocolate pudding.  It is made mostly of oxygen, silicon and the heavier element magnesium.The Outer Core  and the Inner Core are the innermost layers of the Earth.  The outer core The core is made is liquid because it is so hot,  about 5000–6000^oC, but the inner core remains solid iron and nickel because of the pressure pushing down on it from the layers above.  

In class, we made our own clay models of Earth.  We identifiedeach layer by painting them in different colours.

Below are some pictures of our work.
