Anotations

Scope note:

Geomorphic features of the earth's surface formed by natural processes and that have definable composition and range of characteristics, which recur wherever the features are found and that reflect similar surface and subsurface conditions. Typically reserved for features above water. For marine landforms, use "undersea landforms."
