V-shaped Valley

 

What are V-shaped Valleys?

V-shaped valleys have steep valley walls with narrow valley floors.
In cross section it has a "V" shape. 

How are V-shaped Valleys formed?

They are created by fast flowing rivers in the upper course of the river with steep gradients. In the upper course, vertical erosion is more dominant than lateral erosion. As rivers flow downhill quickly, they remove more sediment from the bottom of the stream channel than from the sides. This process is called downcutting.  It can be compared to a knife cutting through a cake.
