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.
The word canyon is generally used only in North America, while the words gorge and ravine are used in Europe and Oceania, though gorge and ravine are also used in some parts of North America.
