U-shaped valley include action of glaciers, form in mountainous region, and wider as well as more gradual base. V-shaped valley is formed by strong streams, erosive, and deeper than they are wide.
What is a valley?
Valleys are low-lying areas of land that have been eroded and washed away by the combined elements of gravity, water, and ice. Some dangle, while others are feeble. They are all in the shape of a "U" or "V."
Humongous frames of snow and ice slowly creep downhill, seeking the least resistance. As the glaciers seep, they start picking up rocks and grind away at the valley floor and sides, forming a "U" and transforming the "V" into a "U." When the glacier melts, it leaves a U-shaped valley where the snow flowed.
U-shaped valleys are formed by glaciers, have a wider and more gradual base, and are found in mountainous areas. Strong, erosive streams form a V-shaped valley that is deeper than it is wide.
Thus, V-shaped valley include options 1, 2, and 4. U-shaped valley is 3, 5, and 6.
