Ascientist discovers a rock that she determines to be a fault. she observes that the hanging wall of the fault is above the footwall.

which type of fault has she discovered?

normal
reverse
strike-slip
horizontal

The answer is; reverse fault

Reverse fault is formed by compressional forces in the crust, while that of normal fault is caused by tension force. The compressional forces caused the crust to fracture and the hanging wall rises above the footwall. The Sierra Madre in southern California is an example of a reverse fault mountain.

The answer is B. reverse
