 Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A fault is classified by ____
 A the number of earthquakes that occur along it B the type of plate boundary it occurs along C the directions in which rocks move along it D distance that rocks move on either side of the faultdistance that rocks move on either side of the fault
Explanation:

Detailed explanation-1: -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.

Detailed explanation-2: -Movement of rock along a fault may occur as a continuous creep or as a series of spasmodic jumps of a few metres during a few seconds. Such jumps are separated by intervals during which stress builds up until it overcomes the frictional forces along the fault plane and causes another slip.

Detailed explanation-3: -Faults are classified according to the direction of relative movement along the fault. The terms hanging wall and foot wall refer to the relative position of the plates after movement.
