Question

Quizplus · Accepted Answer

Faults are fracture planes along which rocks move. The movement can be caused by various factors such as tectonic forces or natural pressure. Displacement can occur along these planes as rocks move past each other. Cracks or fractures may be present in the rocks adjacent to the fault, but they are not the defining characteristic of a fault.
