Structure of the earth

Task descrption: Today I finished my "structure of earth" presentation.At the last slide you will see that I have labled the layers of the earth. The crust is the thinnist layer and the first layer. The next layer will be the mantle. And the last 2 are basically the same, they are both cores and they also are both made of iron and nickel, the only things that are different is the there is a outer core which is just lava, and the inner core which is 90 miles centered from the earth. it is as hot as the sun's surface.
