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.
The convection process pushes the plates, causing them to collide in some places and become separated in others. The separation of two tectonic plates, known as a divergent plate boundary, causes magma to rise to the surface in the gap between the plates. This magma then cools to form new crust, which further pushes the two plates apart.
