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.
. Pothole.
A pothole is a structural failure in a road surface, usually asphalt pavement, due to water in the underlying soil structure and traffic passing over the affected area.[1] Water first weakens the underlying soil; traffic then fatigues and breaks the poorly supported asphalt surface in the affected area. Continued traffic action ejects both asphalt and the underlying soil material to create a hole in the pavement.
.Barchan.
Barchan, also spelled Barkhan, crescent-shaped sand dune produced by the action of wind predominately from one direction. One of the commonest types of dunes, it occurs in sandy deserts all over the world.
.Gorge.
A gorge is a narrow valley with steep, rocky walls located between hills or mountains. The term comes from the French word gorge, which means throat or neck. A gorge is often smaller than a canyon, although both words are used to describe deep, narrow valleys with a stream or river running along their bottom
