Earth Pizza

We use the side view of a pizza slice to model the earth. We are only seeing a very thin part of the crust of the earth.

The crust of the pizza is the bottom layer, which in this case is the asthenosphere. The sauce in under the cheese is the lithosphere. The cheese is more dense then the meat or vegetables, which makes it the oceanic crust.This is everywhere on the earth, and the meat or vegetables is the continental crust, only being on parts of the pizza or earth.
