Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A normal fault forms from what kind of forces?
A
Compression
B
Tension
C
Shear Stress
D
Deformation
Explanation: 

Detailed explanation-1: -A normal fault forms as a result of tensional stress, which occurs when two blocks of rock move away from one another.

Detailed explanation-2: -In terms of faulting, compressive stress produces reverse faults, tensional stress produces normal faults, and shear stress produces transform faults.

Detailed explanation-3: -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-4: -Yes. Normal faults are caused by tension. In a normal fault, the hanging wall is being pulled away from the footwall such that it slips downwards along the fault plane. Tensional forces are responsible for this type of fault movement.

Detailed explanation-5: -Normal faults are caused by tensional stress, or stress that pulls rocks apart.. This small fault is a normal fault because the hanging wall has moved down relative to the footwall.
