Question

Quizplus · Accepted Answer

Joints in rocks are fractures or separations in rocks along which there is no appreciable displacement or movement of the blocks on either side of the fracture. These fractures are typically parallel and can be closely spaced, but they do not involve movement of the blocks in opposite directions as seen in faults. The other options listed (A, B, and D) describe different types of faults or structures that are not associated with joints.
