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 outermost part of the earth, known also as the lithosphere, is broken up into plates that are supported by the underlying mantle. New crust is formed where plates move away from each other under the oceans, and old crust is recycled back into the mantle as where plates moving in opposite directions collide.
