Restless tectonic plates move (shift) between one and fifteen centimeters per "year".

Tectonic  plates refers to a giant chunks of the Earth's outside layer that skim on the asthenosphere, which is the upper part of the mantle of the Earth. The asthenosphere is a semi-liquid layer that twists and moves because of convection flows in the mantle. Plate tectonics is the theory that describes how the movement of tectonic plates and about the results from this movement.  

Tectonic plates move at a moderate rate, around one and fifteen centimeters  per year. The plates move in different ways, once in a while crashing into one another. At different areas they move separated or slide past one another.
