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.
Originally Answered: Why and how do tectonic plates move? The driving force is Convection, or a process by which a fluid will circulate if it is heated from one side and not the other. The mantle is under enough pressure that a significant portion of it is quite plastic, and enough of it is hot enough that it is quite fluid. Source: Plate Tectonics : How Plates Move. Here's a map of the plates' movements: Seems decently consistent with how a surface might be moved by convection currents.
