GEOLOGY

Detailed explanation-1: -normal fault-a dip-slip fault in which the block above the fault has moved downward relative to the block below. This type of faulting occurs in response to extension and is often observed in the Western United States Basin and Range Province and along oceanic ridge systems.

Detailed explanation-2: -It forms when rock above an inclined fracture plane moves downward, sliding along the rock on the other side of the fracture. Normal faults are often found along divergent plate boundaries, such as under the ocean where new crust is forming. Long, deep valleys can also be the result of normal faulting.

Detailed explanation-3: -In terms of faulting, compressive stress produces reverse faults, tensional stress produces normal faults, and shear stress produces transform faults.

Detailed explanation-4: -A normal fault forms as a result of tensional stress, which occurs when two blocks of rock move away from one another. These types of faults form along divergent boundaries, which are boundaries where two tectonic plates separate from one another such as those found at seafloor ridges.
