Answer the following question given this paragraph: A strike-slip fault is a dip-slip fault where the dip of the fault plane is vertical. Strike-slip faults result from shear stresses. If you stand with one foot on each side of a strike-slip fault, one side will be moving toward you while the other side moves away from you. If your right foot moves toward you, the fault is known as a right-lateral strike-slip fault. If your left foot moves toward you, the fault is a left-lateral strike-slip fault ( Figure below ). Q: What is a dip slip fault where the dip of the fault plane is vertical? A:

Choices: (I). strike - theory. (II). reverse slip. (III). incline slip. (IV). strike-slip.
The answer is:
(IV).
