How do normal faults differ from reverse faults?

In a Normal Fault, the hanging wall moves downwards relative to the foot wall. They are caused by extensional tectonics. This kind of faulting will cause the faulted section of rock to lengthen. In a Reverse Fault, the hanging wall moves upwards relative to the foot wall.
