Question 1

How does movement in a normal fault differ from that in a reverse fault?

Accepted 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.
