A ridge can occur as either an isolated, independent feature or part of a larger geomorphological and/or structural feature.

20-572: Is used by the USA National Cooperative Soil Survey Program to classify ridges and other landforms.

The groups and their subgroups are not mutually exclusive; landforms, including ridges, can belong to multiple subgroups. In this classification, ridges are found in
25-434: The surrounding terrain by steep sides. The sides of a ridge slope away from a narrow top, the crest or ridgecrest , with the terrain dropping down on either side. The crest, if narrow, is also called a ridgeline . Limitations on the dimensions of a ridge are lacking. Its height above the surrounding terrain can vary from less than a meter to hundreds of meters. A ridge can be either depositional , erosional , tectonic , or
