Near its source, a river flows very fast. The rushing water wears away the surrounding rock. This widens and deepens the river channel, forming a gorge or V-shaped valley.
A V-shaped valley is formed when a flowing river cuts into the earth. The valley gets its V shape when rain and runoff flow down the banks of the river, causing erosion; V-shaped valleys are most commonly found in the mountains. The V-shaped valley gets its name because when looked at from the front, it looks like the letter V.
Yosemite Valley is one of the most popular V-shaped Valleys. It is located in the Yosemite National Park in California.
