GEOLOGY

Detailed explanation-1: -This fault motion is caused by compressional forces and results in shortening. A reverse fault is called a thrust fault if the dip of the fault plane is small.

Detailed explanation-2: -Reverse or Thrust Faults: The opposite of a normal fault, a reverse fault forms when the rocks on the “uphill” side of an inclined fault plane rise above the rocks on the other side. Reverse faults often form along convergent plate boundaries.

Detailed explanation-3: -A reverse fault is formed by compressional stress, where two blocks of rock push against one another. When compressional stress occurs, the footwall and hanging wall are pushed together, and the hanging wall rises and moves upward above the footwall. Reverse faults are also known as thrust faults.

Detailed explanation-4: -In terms of faulting, compressive stress produces reverse faults, tensional stress produces normal faults, and shear stress produces transform faults.

Detailed explanation-5: -Figure 10.22b: Compressional forces typically push the hanging wall upward relative to the footwall, producing a reverse fault.
