What is a characteristic of a reverse fault?

1. Horizontal displacement only

2. Vertical displacement with compression

3. Movement along a strike plane only

4. None of the above

The correct answer is: Vertical displacement with compression

A reverse fault is characterized primarily by vertical displacement resulting from compressive forces. In this type of fault, the hanging wall moves up relative to the footwall, which occurs due to the compression of the Earth's crust. This movement leads to a shortening of the crust in the area where the fault is located. The other options do not accurately describe the nature of a reverse fault. Horizontal displacement only refers to lateral movement, which is not a feature of reverse faults as they primarily involve vertical motion. Movement along a strike plane only implies horizontal slipping without any vertical component, which is more characteristic of strike-slip faults. Therefore, the defining characteristic of a reverse fault is indeed the vertical displacement that occurs due to compressive forces acting on the crust.
