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).
You probably know that the Earth's crust is broken up into huge tectonic plates that slide under, over and past each other, slowly building mountains, forming new oceans and triggering earthquakes.
