The term tectonics comes from the Greek word tektonikos, which means "building or construction," and refers to the deformation of the earth's crust caused by internal forces. The theory of plate tectonics identifies 7 major and 20 minor types of lithospheric plates.

There are four types of plate boundaries: Divergent boundaries -- where new crust is generated as the plates pull away from each other. Convergent boundaries -- where crust is destroyed as one plate dives under another. " - Theory of plate tectonics class 9
