In [[geology]], a '''valley''' or dale is a depression with predominant extent in one direction. A very deep [[river]] valley may be called a [http://en.wikipedia.org/wiki/Canyon canyon] or gorge.

The terms U-shaped and V-shaped are descriptive terms of geography to characterize the form of valleys. Most valleys belong to one of these two main types or a mixture of them, at least with respect of the cross section of the slopes or hillsides.

A valley in its broadest [[geographic]] sense is also known as a ''dale''. A valley through which a [[river]] runs may also be referred to as a ''vale''. A small, secluded, and often wooded valley is known as a [http://en.wikipedia.org/wiki/Dell_(landform) dell] or in Scotland as a glen. A wide, flat valley through which a river runs is known in Scotland as a ''strath''. A [http://en.wikipedia.org/wiki/Cove_(Appalachian_Mountains) mountain cove] is a small valley, closed at one or both ends, in the central or southern [http://en.wikipedia.org/wiki/Appalachian_Mountains Appalachian Mountains] which sometimes results from the [[erosion]] of a geologic window. A small valley [[surrounded]] by [[mountains]] or ridges is sometimes known as a ''[[hollow]]''. A deep, narrow valley is known as a ''coon'' (also spelled ''combe'' or ''coombe''). Similar geological structures, such as [http://en.wikipedia.org/wiki/Canyon canyons], [http://en.wikipedia.org/wiki/Ravine ravines], gorges, [http://en.wikipedia.org/wiki/Gully gullies], and kloofs, are not usually referred to as valleys.[http://en.wikipedia.org/wiki/Valley]
