What type of force creates a normal fault?

Compression
|
|
Tension
|
|
Shearing

Confining

Explanation:
Detailed explanation-1: -In terms of faulting, compressive stress produces reverse faults, tensional stress produces normal faults, and shear stress produces transform faults .
Detailed explanation-2: -Normal faults result from tensional forces when rocks are displaced away from each other. Reverse faults results of compressional forces when rocks are displaced towards each other. Strike-slip or transform faults results from either compressional or extensional forces when rocks slip parallell to each other.
Detailed explanation-3: -In a normal fault, the hanging wall moves downward below the footwall. Normal fault stress is known as tensional stress, which creates a tension fault where two plates move apart from one another.
