Crust
The Crust is the thiner-most layer in the Earth. The crust is made up of large rocks. The Crust has two major depths, one in the ocean, and the other one on land. The depth on land can go as far as 60 km. But the furthest the crust goes in the ocean is about only 6 km. The Crust is right under what you are standing on right now. It is almost getting bullied (metaphorically) by the Mantle, because when the Convection Currents in the Mantle push the Crust apart, the Crust will open up and that will create either an earthquake, tsunami, or volcano.
