Best Answer: The Earth is made up of plates(continental or oceanic) that move becuase of the convection currents that occur in the mantle. As this plates move they drift apart(when crust is formed), collide(crust is destroyed) or pass by each other(causes friction generating faults or earthquaques).
The Earth's Crust. At the very surface of the Earth is the crust, the topmost layer, made mostly out of solid silicate rocks like basalt and granite. The crust is like the icing on a cake, though not nearly so tasty. We humans live on top of the crust; you can think of us as the strawberries or gummy bears on the top of the cake.
