What type of fault usually occurs because of compression?

a. folded

c. strike-slip

b. normal

d. reverse

The type of fault that occurs because of compression is the reverse fault. The answer to this item is letter D. By definition, this type of fault occurs when the fault line is displaced upward relative to the rock below the fault line. This is opposed to the description of the gravity fault.

Reverse faults form because of the process of compression. (d. reverse). Reverse faults are formed when the hanging wall moves up relative to the foot wall. Convergent plate margins occur where tectonic plates come together. Reverse faults are usually formed along these plate margins.
