Answer:

Many things.

Explanation:

The earth has 4 main layers. The crust, mantle, outer core, and the inner core. The crust is where we live, and is thin and rocky. The mantle has convection currents running through it, and is more dense than the crust. The mantle is the thickest layer. The outer core is liquid and very hot. The inner core is a solid ball, which is in the center of the earth.
