GEOLOGY

Detailed explanation-1: -normal fault-a dip-slip fault in which the block above the fault has moved downward relative to the block below.

Detailed explanation-2: -When rocks slip past each other in faulting, the upper or overlying block along the fault plane is called the hanging wall, or headwall; the block below is called the footwall.

Detailed explanation-3: -A reverse fault is one in which an upper block of rock slides over a lower block which is separated from it by the fault.

Detailed explanation-4: -The hanging wall is the block of rock that sits above the fault plane; whereas, the footwall is the block of rock that sits below the fault plane. Compressional faults are produced through compression (shortening or pushing together) of the crust causing the hanging wall to move up relative to the footwall.

Detailed explanation-5: -Normal faults result from tensional forces when rocks are displaced away from each other. Reverse faults results of compressional forces when rocks are displaced towards each other. Strike-slip or transform faults results from either compressional or extensional forces when rocks slip parallell to each other.
