Faulting can also result in mountain building. The movements of plates within the earth's crust can cause rock strata to break and be displaces. The rocks may crack or fracture and give rise to structural changes within the earth's crust. In faulting, each side of fracture is termed a fault. The place where the fault occurs is the fault plane. The slope between the two faults is termed as the fault scrap.
With different plate movements within the earth' crust, several kinds of faults may be produced that are listed below:
1 Normal fault: when plates move away from each other tensional forces cause the rocks to break and fall, with an up throw block on the top and a down throw block at the bottom.
2 Reverse fault: when plates move into each other, compressional forces push up one stratum, so that it rides over the other stratum.
3 Tear fault: this occurs only when the two parts of the land slide past each other horizontally.
4 Thrust fault: the thrust fault is fairly similar to the reverse fault, where compressional forces squeeze the blocks at the diagonal angle, resulting in an up throw block standing above the down throw block below.
