Detailed explanation-1: -If rocks on one side of the break shift relative to rocks on the other side, then the fracture is a fault. If there is no movement of one side relative to the other, and if there are many other fractures with the same orientation, then the fractures are called joints.
Detailed explanation-2: -There are two types of fractures in rock: joints and faults. A joint is a fracture along which no movement has taken place. Tensional forces generally cause joints. A fault is a fracture or break in the rock along which movement has taken place.
Detailed explanation-3: -Faults are fractures in Earth’s crust where movement has occurred.
Detailed explanation-4: -An articular or periarticular fracture happens when a bone breaks inside or around a joint. These injuries often damage cartilage at the ends of bones (articular cartilage) and other joint tissues, requiring special care.
Detailed explanation-5: -Fractures in rock along which movement has occurred are called Faults while fractures in rock along which the only separation has occurred are called Joints. In a fault fracture the rock on either side will move relative to one another and move parallel to the plane.
