What is a model of the earths surface?

If the question is referring to being seen from above, the answer is a map!

A model of the Earth's surface would be something showing the inner and outer core, the lower and upper mantle, and the crust. 

There are actually other layers, but these are the main ones that are usually required. I used those in Bio, but I used the other ones in AP Bio. If you need the others, let me know!

Is their a picture that goes along with it? ?
