Explanation:

A fault is a fracture which is a product of brittle deformation of the crust. It is a displacement of the earth crust in which a noticeable movement has occurred.

For a fault to result, a rock must behave in a brittle way in reaction to the applied stress.

Stress is the force per unit area acting on a surface of rock.

There are three major types of faults:

1. Normal faults

2. Thrust or Reverse faults

3. Hybrid faults.

The fault shown in the diagram is a reverse fault. A reverse fault is one in which the the footwall has moved downward and the hanging wall upward.

For a reverse fault to result, the direction of stress in the body of rock must be a compressional one.

A compressional stress is one in which the direction of stress is towards one another. The stress acts to keep the rock together but then forces a displacement.

Compressional stress results in thickening of the crust and produces folds where a rock is ductile and reverse faults in brittle rocks.

Compression results in shortening of the crust and thus reverse fault.

Arrows B and D causes tensional stress yeilding elongation of the crust. They seems to be pulling the rocks apart. The faults associated with them are normal faults.

Normal faults are extensional faults.

Hybrid faults combines features of both normal and reverse faults.
