RIDGE

In geography, a ridge describes a land form which rises to a maximum line or crest. It is distinguished from a range, which consists of more than one ridge. A ridge with uniform slopes is called a hog's back; if one slope is steep and the other gentle, they form a scarped ridge. For submarine forms, the term ridge is used to describe a relatively narrow elevation, which is prominent on account of the steep angle at which it rises.
