Question

the image shows a type of fault. what stress causes this type of fault to form? compression gravity tension shearing

Explanation:

Compression causes reverse - type faults where the hanging wall moves up relative to the footwall. Gravity is a force but not the direct stress for this fault type. Tension causes normal faults. Shearing causes strike - slip faults. The image shows a normal fault which is formed by tension as it stretches the rock and causes the hanging wall to move down relative to the footwall.
