In which type of fault does the hanging wall slide up and over the footwall?
A
strike-slip
B
normal
C
reverse
D
None of the above
Explanation: 

Detailed explanation-1: -A reverse fault is one in which the hanging wall moves up relative to the footwall.

Detailed explanation-2: -Reverse faults are exactly the opposite of normal faults. If the hanging wall rises relative to the footwall, you have a reverse fault. Reverse faults occur in areas undergoing compression (squishing).

Detailed explanation-3: -In reverse faults, the hanging wall moves upwards relative to the footwall. This motion can be determined by tracing the offset of the beds in a vertical motion in a block diagram. In map view, the hanging wall rocks will be older than the footwall rocks, due to erosion of the uplifted side (Figure 15).

Detailed explanation-4: -Fault is a fracture or crack where two rock blocks slide past one to another. If this movement may occur rapidly, it can be causes earthquike or slowly, in the form of creep. Types of faults include strike-slip faults, normal faults, reverse faults, thrust faults, and oblique-slip faults.

Detailed explanation-5: -There are three main types of fault which can cause earthquakes: normal, reverse (thrust) and strike-slip. Figure 1 shows the types of faults that can cause earthquakes. Figures 2 and 3 show the location of large earthquakes over the past few decades.
