That is because its outer surface is composed of about 20 tectonic plates, enormous sections of Earth's crust that roughly fit together and meet at places called plate boundaries. Each plate is moving in a different direction, but the exact direction depends on the reference frame, or viewpoint, in which you are looking at the motion. one plate moves underneath the other plate and sinks into the mantle.
