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