Detailed explanation-1: -Faults are cracks in the earth’s crust along which there is movement. These can be massive (the boundaries between the tectonic plates themselves) or very small. If tension builds up along a fault and then is suddenly released, the result is an earthquake.
Detailed explanation-2: -A fault is a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative to each other. This movement may occur rapidly, in the form of an earthquake-or may occur slowly, in the form of creep. Faults may range in length from a few millimeters to thousands of kilometers.
Detailed explanation-3: -When rocks on either side of a nearly vertical fault plane move horizontally, the movement is called strike-slip.
Detailed explanation-4: -A fault trace describes the intersection of a geological fault with the Earth’s surface, which leaves a visible disturbance on the surface, usually looking like a crack in the surface with jagged rock structures protruding outward. The term also applies to a line plotted on a geological map to represent a fault.
Detailed explanation-5: -A fault is formed in the Earth’s crust as a brittle response to stress. Generally, the movement of the tectonic plates provides the stress, and rocks at the surface break in response to this. Faults have no particular length scale.
