What Causes the Earth Plates to Move?

Plate tectonics describes the plates of the Earth’s surface and how they move. The plates continually shift because they are resting on the mantle, which is hot and soft. The mantle moves slowly, like a conveyor belt, and other forces originating in the Earth’s core contribute to the motion. Currently, the plates are moving up to 15 centimeters a year in various directions. For more information look here:
