Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
what is it called when the dip of a dip slip fault is vertical?
A
normal fault
B
strike-slip fault
C
reverse fault
D
fracture
Explanation: 

Detailed explanation-1: -A fault that has a component of dip-slip and a component of strike-slip movement is termed an oblique-slip fault.

Detailed explanation-2: -The general term of “dip-slip faults” is given to faults where there is vertical movement along the fault plane. Fault planes can become mineralized (form a channel for mineralizing fluids). Faults are classified according to their relative motion: Normal Fault: hanging wall has dropped relative to the footwall.

Detailed explanation-3: -Normal and reverse faults display vertical, also known as dip-slip, motion. Dip-slip motion consists of relative up-and-down movement along a dipping fault between two blocks, the hanging wall and footwall. In a dip-slip system, the footwall is below the fault plane and the hanging wall is above the fault plane.

Detailed explanation-4: -There are three types of dip-slip faults: normal, reverse, and thrust. The character of the movement (offset) along the fracture plane determines what kind of dip-slip fault it is.

Detailed explanation-5: -Faults which move along the direction of the dip plane are dip-slip faults and described as either normal or reverse (thrust), depending on their motion. Faults which move horizontally are known as strike-slip faults and are classified as either right-lateral or left-lateral.
