What happens along a fault beneath earth's surface when an earthquake occurs?

Earthquakes occur on faults. A fault is a thin zone of crushed rock separating blocks of the earth's crust. When an earthquake occurs on one of these faults, the rock on one side of the fault slips with respect to the other. ... The fault surface can be vertical, horizontal, or at some angle to the surface of the earth.

The correct answer is a)  a resource with a limited supply; it will run out.
