From what I was taught at school, I got a fairly clear (I thought) picture of how the earth was laid out: first there was a thin layer of grass, about an inch thick. Then there was the dirt - about half a meter of it, with stones in. Then there was a layer of dinosaur bones, for about another half a meter, and then there was all the hot metal in the centre of the earth. I always drew my pictures with this in cross-section.
