Question

Which statements describe reverse faults? Check all that apply.

A) The hanging wall moves up.
B) The hanging wall moves down.
C) The fault is at an angle.
D) The fault is caused by compression.
E) The fault is caused by tension.
F) The plates are colliding.
G) The plates are moving away from each other.

Answer 1

Correct choices: A, C, D, F.

Brief reasons:
- A: True — in a reverse fault the hanging wall moves up relative to the footwall.
- C: True — reverse faults are inclined (angled) faults (thrust faults are a low-angle variety).
- D: True — reverse faults form under compression.
- F: True — plate collision (convergent boundaries) produces the compression that causes reverse faults.

B and E are for normal faults (hanging wall moves down; caused by tension). G describes divergent plate motion, which produces normal faults.
