Smoothly curved fracture, or fractures, in a rock.

Joints can be small or up to thousands of feet long. Hundreds of joints may appear in a single outcropping of rock.

A joint system consists of two or more sets of joints that are arranged in characteristic patterns; such as, concentric, radial, etc.

The jointing of rock formations is a major factor of geological changes resulting from weathering and erosion.

The movement of the rock at right angles to this fracture can produce an open joint, or fissure. If the movement of the rocks of a joint is parallel to the surface of the fractures, the resulting break is classified as a fault.

A business; for example, a bar or a nightclub, that charges its customers much more money than that which seems to be normal: Mike complained to the waitress that the bill for the meal made him feel that he was in a clip joint.

The joint on the hind limb, or leg, located between the lower thigh and the rear pastern: The hock joint is very complex and is made up of many bones, including the tibia, fibula, and the talus.

A dog walks on its toes like a horse, not the soles of his feet like a bear or a human. The human wrist is analogous to the canine pastern joint, the back of the hand is the dog's pastern, and the fingers form the dog's paws.
