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 police raided the clip joint in their search for those who were selling illegal drugs.

A space, or spaces, that are left in structures, roads, or streets which allow for the expansions and contractions of the materials which are caused by heat and cool environments.
