Ravines and gullies are erosional features that exist on a continuum of scales. A ravine is defined as a small, narrow, and deep depression, smaller than a valley, and larger than a gully (Bates and Jackson, 1984). Both grow by head cutting. Ravines are usually longer and deeper than gullies. Gullies may be small enough to plow, these are ephemeral gullies.
Canyon and gorge are somewhat interchangeable, depending on regional semantics, and describe a condition of land scoured or carved out by rivers (or wind), creating deep gouges in the earth of varying depths. A valley is usually a discernable low spot in the land, probably created by tectonic action or glacier movement.
