These faults are generally steeply dipping, with a dip angle of 60° or greater. Low-angle normal faults have a dip of below 45°, accomplishing more extension per unit slip. How these faults are able to form and slip at such a low angle is a mechanical mystery.

The surface of the ocean then fades away and the animation pulls back to show the global thermohaline circulation,” (Olsen et al 2013). The ice formation increases the salinity of the frigid surrounding waters, producing some of the densest seawater in the world.

Depth contours, shoreline configurations, and interactions with other currents influence a current's direction and strength.

When no displacement has occurred after the fracture has formed, this fracture is called a joint; if displacement by sliding has occurred, it is a fault; and if opening has happened, it is called a fissure.

Terminology for strike-slip faults has evolved based on the spatial scale and context of faulting.

As this displacement accumulates, faults tend to form a zone of fractured rock around them, called a damage zone, and form a zone of fault gouge along the slip surface. Thus, faults with significant offset appear very different from joints.

Reverse faults are generally recognized by the emplacement of older rocks above younger ones, though in areas of complex deformation this is not always the case. These faults often dip at low angles, generally lower than 30º, and so are called thrust faults. All thrust faults are also reverse faults.
