'''Faults''' are fractures or fracture zones in the [[Earth]]'s crust along which one side moves with respect to the other. A fault scarp is a cliff or steep slope that sometimes forms along the fault at the surface. There are many types of faults (for example, strike-slip, normal, reverse, and thrust faults) ranging in size from a few tens of meters to hundreds of [[kilometer]]s in dimension. When faults occur along crustal plate boundaries, such as with the [[San Andreas Fault]] in [[California]], they are called ''transform boundaries''. | '''Faults''' are fractures or fracture zones in the [[Earth]]'s crust along which one side moves with respect to the other.
