Plate Tectonics

In addition to convergence and divergence, transform motion may occur along plate margins. Transform margins, in many ways, are less spectacular than convergent and divergent ones, and the type of plates involved is really of no significance. Along transform margins, about all that occurs are faults and earthquakes. Plate movement produces the earthquakes, as the two rock slabs slide past one another. The best known example of a transform plate margin is the San Andreas fault in California, where the Pacific and North American plates are in contact.
