Transcription: A fault is a fracture in the Earth's crust characterized by an uneven crack that may run for many kilometers. The two sides of the fault line are actually two gigantic moving sections or plates of the Earth's crust. The crack in the Earth is created because one plate is moving relative to the other. When the plates move past each other, the relative motion is horizontal and we have a strike-slip fault. The San Andreas Fault, for example, is a strike-slip fault. When the plates press toward each other, large blocks of rock may be lifted up, producing thrust faults. When plates move away from ea ...
