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. Other names: thrust fault, reverse-slip fault or compressional fault].

Detailed explanation-2: -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-3: -If the angle of the reverse fault is low (<15°), the fault is called a thrust fault. A thrust fault is a special type of reverse fault because it has a low angle. Thrust faults are also the result of extreme compressional stress, such as occurs when tectonic plates come together to form mountains.

Detailed explanation-4: -Compressional stress is when a rock is pressed together into itself, like when crust movements cause two rocks to squeeze another one between them. Another example is when mountains are formed at a convergent boundary, like the Rocky Mountains.

Detailed explanation-5: -reverse (thrust) fault-a dip-slip fault in which the upper block, above the fault plane, moves up and over the lower block. This type of faulting is common in areas of compression, such as regions where one plate is being subducted under another as in Japan.
