Because the V-shaped valley constrains the movement of the glacier, its force is concentrated in the floor. 0 Answers/Comments . It is actually due to their peculiar positioning and structure above their main valleys. V-shaped valleys are formed by the erosive effects of running water and U-shaped valleys are formed by the erosive effects of flowing glacial ice. The size of the flowing glaciers is responsible for the size of the valleys thus formed. Log in Sign up. read more, U-shaped valleys, trough valleys or glacial troughs, are formed by the process of glaciation. The hanging valleys formed in this way have U-shaped walls. Often, they take the easiest path, occupying the low V-shaped valleys once carved by rivers. U-shaped valleys are created once the glacier recedes. There is typically river or stream running in the bottom of the valley but not always, some valleys are dry.
