A reverse fault is typically formed under which stress regime?

Explanation:
Reverse faults form when rocks are squeezed in compression, shortening the crust so the hanging wall moves up relative to the footwall. This compressional regime is typical at convergent plate boundaries where plates push toward each other. Under tension, rocks are pulled apart and normal faults form with the hanging wall moving down. Shear stress yields strike-slip faults with predominantly lateral movement and little vertical displacement. Gravitational forces can cause movement, but they don’t define the tectonic stress regime that creates a reverse fault.
