Ridge

A ridge is a long, narrow, elevated geomorphologic landform, structural feature, or a combination of both separated from the surrounding terrain by steep sides.

Frequently, a ridge can be further subdivided into smaller geomorphic or structural elements.

[1][2][3] As in the case of landforms in general, there is a lack of any commonly agreed classification or typology of ridges.

They can be defined and classified on the basis of a variety of factors including either genesis, morphology, composition, statistical analysis of remote sensing data, or some combinations of these factors.

In this classification, ridges are found in the Aeolian, Coastal Marine and Estuarine, Lacustrine, Glacial, Volcanic and Hydrothermal, Tectonic and Structural, Slope, and Erosional subgroups.
