Answer to Question 1

Answer: A

Answer to Question 2

Answer: In a normal fault, movement along the fault is caused by tensional stress in the crust; this causes the hanging wall to move downward with respect to the footwall. In a reverse fault, movement along the fault is caused by compressional stress in the crust; this causes the hanging wall to move upward with respect to the footwall.
