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.
Plate movement causes the buildup of tremendous quantities of energy in the rock. When the energy is released, it produces vibrations that travel through the rock, leading to earthquakes. During earthquakes, faults, or giant cracks, are produced by the pressure of the moving rock. Earthquakes and volcanoes occur along the edges of the plates. Scientists have developed a theory that explains how these giant plates move, thereby creating, destroying, and re-forming continents and oceans over long periods of time. This theory is called the theory of plate tectonics.
