A ridge is a long, narrow, elevated strip of land or any raised strip or band. A ridge is a line that rises above what it is attached to.

Think of a ridge as a combination between rim and edge. From the Old English hrycg, meaning “back of the man or beast” or “the top or crest” of something (combined, the senses mean “backbone”), ridge is often used for the beam that joins the parts of a sloping roof. Ridge also refers to the line formed by hills or mountains, as in the Blue Ridge Mountains. The Mid-Atlantic Ridge is made up of mountains that lie underneath the Atlantic Ocean.
