A: The three primary causes for tectonic plate movement are the convection of material in the mantle, gravity and the rotation of the planet. These forces cause each of the seven major plates and numerous other microplates to move independently of the others at a rate of a few centimeters per year.

There are several different hypotheses to explain exactly how these motions allow plates to move. Plate Tectonics are what cause the Earth's plates t move.
