Question

Quizplus · Accepted Answer

Joints form when rock fractures, but there is no movement along the fracture. Faults form when rock on one side of a fracture moves relative to the rock on the other side. Therefore, the main difference between joints and faults is that joints form in place, whereas faults are the result of rock movement. Choices A, B, and D are incorrect because they do not accurately describe the difference between joints and faults.
