Detailed explanation-1: -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.
Detailed explanation-2: -Faults are cracks in the earth’s crust along which there is movement.
Detailed explanation-3: -A fault is a break in the Earth’s crust along which blocks of the crust slide relative to one another. D. Earthquakes occur along faults because of this sliding.
Detailed explanation-4: -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.
Detailed explanation-5: -The plates slide under or past one another, stressing the stone along the sides of each plate. When the stress on the rock is great enough, it causes a fracture between two blocks of rock, allowing the blocks to move relative to each other. Then a long crack forms on the Earth’s surface, which is called the fault line.
