What are U-shaped valleys used for?
glacial valleys valley is converted to a U-shaped valley because the U-shape provides the least frictional resistance to the moving glacier. Because a glacier has a much greater viscosity and cross section than a river, its course has fewer and broader bends, and thus, the valley becomes straighter and smoother.

What is the difference between valley and mountain?
A valley runs between mountains at the cross-section of the slopes. It is a long gap seen between mountains. Valley serves as the route for rivers to flow towards the lower grounds or plains. Valleys run between hills or mountains, usually, a river flowing through them.
Why do V-shaped valleys occur?
V-shaped valley Rivers begin high up in the mountains so they flow quickly downhill eroding the landscape vertically. As the river erodes downwards the sides of the valley are exposed to freeze-thaw weathering which loosens the rocks (some of which will fall into the river) and steepens the valley sides.
What is called Valley?

How do stream valleys deepen widen and lengthen?
Landscapes on Earth’s surface evolve over time with the main cause of change being streamflow and the resulting erosion and deposition. Uplift sets a new base level which causes streams to cut deeper, resulting in widening of valleys and erosion of hills.
