Question

Quizplus · Accepted Answer

A reverse fault is a type of dip-slip fault where the hanging wall rock moves up compared to the footwall. Therefore, option B is the correct choice. Option A describes a normal fault, not a reverse fault. Option C and D refer to the angle of the fault dip, which is not specific to a reverse fault.
