Answer
The three fault types are normal, reverse, and transcurrent (Strike-Slip).
- When the hanging wall collapses, common defects
appear. Pulling the sides apart, also known as extensional forces, is what causes normal defects.
- The rising hanging wall causes reverse defects to emerge. Compressive pressures are what push the sides together to form reversal faults.
- Walls in strike-slip or transcurrent faults slide laterally rather than vertically.
