A valley itself cannot cause erosion, but can be hugely affected by erosion. Usually Valley erosion is caused by glaciers, a common agent of erosion.
In cross-section: A 'U' shaped valley is formed from glacial erosion. A 'V' shaped valley is formed by river erosion.

A 'U' shaped valley is one that has been gouged out by glacial action. A 'V' shaped valley is one that has been caused by river erosion.
Generally soil erosion caused by water, wind or both.
The entire valley is from erosion and glaciers.
