Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A normal fault is created by what type of stress?
A
tension
B
compression
C
shearing
D
none of these
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 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.

Detailed explanation-3: -Normal Faults: This is the most common type of fault. 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.

Detailed explanation-4: -Answer and Explanation: A normal fault usually occurs because of tension.

Detailed explanation-5: -In geology, the term “tension” refers to a stress which stretches rocks in two opposite directions. The rocks become longer in a lateral direction and thinner in a vertical direction.
