What type of force is associated with a strike-slip fault?

• A. Tension
• B. Compression
• C. Shear
• D. Gravity

Answer: (C)

A strike-slip fault is primarily associated with shear forces, which arise when two blocks of crust slide past one another horizontally. This type of fault operates along vertical planes, with the movement of the rocks along the fault line predominantly occurring in a lateral manner. Shear forces are essential in understanding the dynamics of strike-slip faults, as they exert forces that cause the rocks to twist or slide against one another without significant vertical displacement. This movement can lead to seismic activity, as the stress builds up and is released during an earthquake. In contrast, tension and compression are forces that act to stretch or compress rocks, respectively, which are associated with different types of faults—such as normal faults (tension) or reverse faults (compression). Gravity, while a significant force in many geological processes, does not directly describe the movement associated with strike-slip faults.
