Which term describes a fracture in a rock mass along which movement has occurred?

Explanation:
Movement along a fracture means the rocks on either side have slid past one another. The term that describes this is fault. A fault forms when stress causes blocks to move along the crack, creating offset that can be seen in rocks and landscapes. In contrast, a joint is a fracture with no movement between the sides, and a fissure is just a crack or opening without displacement. Rupture is a general term for breaking, not specifically indicating movement along a fracture in geology. So the fracture along which movement has occurred is a fault.
