What is the difference between a joint and a fault?

Joints and faults are types of fractures. A joint is a fracture along which no movement has taken place, usually caused by tensional forces. A fault is a fracture or break in the rock along which movement has taken place. One might expect more earthquakes to occur near faults.

Explanation:

Fractures include joints and flaws. A joint is a fracture along which there has been no movement, which is generally generated by tensional pressures. A fault is a fracture or break in the rock that has allowed movement to occur. Near faults, more earthquakes are likely to occur.
