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.
In the United States, place names generally use canyon in the southwest and gorge in the northeast, with the rest of the country graduating between these two according to geography. In Canada, gorges are usually narrow, and ravines more open and often wooded.
