Valley
A valley is (1) an elongated hollow between hills or mountains, (2) a trough between mountain ridges, (3) a particular part of a land area watered by a river.
-Hanging Valley
A hanging valley is a tributary valley situated above a major valley. A waterfall at the and of this hanging valley is a common feature.
The hanging valley is formed by greater erosion by the glacier in the main valley. The glacier also cuts off the ends of the land between adjacent hanging valleys, creating truncated spurs.

-V-shaped Valley
A valley that has been created by the force of river erosion. It has evenly sloping sides, in contrast with U shaped valleys, which have much steeper sides. The upper courses of most unglaciated river valleys are V-shaped, although the shape is influenced by other factors, being erosion in more humid climates, while in more dry climates the V may be steep and narrow. Even the difference in sunlight exposure may cause a valley to develop an uneven V-shape due to difference in vegetation and erosion on the sunny and shady slopes.
The structure of the rock will also affect the shape of the valley.

-U-shaped Valley
The U-shaped valley is also known as a glaciated valley. The glacier not only occupied the valley floor, but also the sides. Downward movement caused over-steepened sides and smoothened out irregularities on the valley floor, although bars of highly resistant rock may remain. There may be 'hanging valleys on the sides.
