Question

Given below are two statements:
Assertion (A): A dip-slip fault can be a wrench fault.
Reason (R): Along a dip fault, the net slip can be equal to strike-slip, dip-slip or oblique-slip.

• A. Both A and R are correct and R is the correct explanation of A
• B. Both A and R are correct but R is not the correct explanation of A
• C. A is correct but R is not correct
• D. A is not correct but R is correct

Hint:

Dip-slip faults move along dip direction, while wrench faults are strike-slip faults.

Answer 1

The Correct Option is D

Concept:
Faults are classified according to the direction of slip relative to the fault plane.

Step 1: Check Assertion.
A dip-slip fault involves movement mainly along the dip direction. A wrench fault is mainly a strike-slip fault. \[ A \text{ is not correct} \]

Step 2: Check Reason.
Net slip on a fault may be strike-slip, dip-slip or oblique-slip depending on the movement direction. \[ R \text{ is correct} \]

Step 3: Final conclusion.
Assertion is incorrect, but Reason is correct. \[ \therefore \text{Correct Answer is (D)} \]
