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.
Why do tectonic plates move? The main driving force of plate tectonics is gravity. If a plate with oceanic lithosphere meets another plate, the dense oceanic lithosphere dives beneath the other plate and sinks into the mantle: this process is called subduction. However, convection is also driving plate tectonics. When you heat up noodles in a pan of water, you create convection cells: noodles move upward in the middle of the pan where temperature is higher, and downward on the edges of the pan where the temperature is lower.
