Question:

In your own words, explain the processes responsible for the formation of a reverse fault.

Answers

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).

Reverse fault is formed by compression of shortened horizontal side of a normal fault.

Explanation:

A reverse fault is formed when the movement of earth (either contraction or shortening) produces horizontal forces that are compressive in nature. These faults results from the normal faults that are opposite to each other.  

A reverse fault comprises two main activities – a) shortening of  horizontal distance on either side of a normal fault and b) Compression of this fault.

Process responsible for the formation of a normal fault.

Explanation:

A normal fault is formed when the steep sidewall suddenly drops downwards about the fault. May be caused by the external forces that pull them apart such as gravity and they can be most commonly seen in the divergent boundaries of the plates. The movement of the plates within the earth takes place and thus their motion results into a force that weakens the rocks and makes the two ends of the steep-sided walls rotate and this pattern creates a push and pulls effect as it does with the slabs of rocks that go into the trench deep inside the earth. Fault formation is an erosional feature of the earth tectonic activities and these get created by the major upliftment of new geomaterial form below like the release of gases.

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. If you imagine undoing the motion of a reverse fault, you will undo the compression and thus lengthen the horizontal distance between two points on either side of the fault.
if you stood on the fault plane the block on the right would be under your feet. this is thus the footwall. The tan sandstone has been pushed up and over itself. This offset of the hanging wall indicates that this is a reverse fault.

The lateral faults are created because of the immense force and pressure from the Mantle layer of the Earth towards the Crust layer, which breaks under that force and pressure. The Mantle layer is a layer of magma, melted metals, that has very high temperature and thus pressure. On certain points on the Earth, the Crust layer is thinner and cracks. That is accompanied by volcanic activity, earthquakes or both. Once the Crust is broken by the pressure and force from beneath, the pressure and force from the Mantle layer moves bit by bit in certain direction.

The process that is responsible for the formation of a normal fault is 
when horizontal stresses occurs in brittle rocks and the hanging wall blocks moves down relative to the footwall blocks

hope  this helps
