(b). U-shaped valley and V-shaped valley
Answers
✳✳DIFFERENCE BETWEEN U SHAPED AND V SHAOED VALLEY------⤵⚫⤵⚫⤵⚫⤵⚫⤵⚫
⚫Glaciers cut distinctive U-shaped valleys with a flat floor and steep sides. The glacier widens, steepens, deepens and smoothes V-shaped river valleys, eg Great Langdale Valley in the Lake District.
⚫U-shaped valleys are typically carved by a glacier. Such landforms are very common in previously glaciated mountainous areas. V-shaped valleys are even more common because they are usually eroded by running water. This is not an exhaustive classification. There are more valley types. Tectonic valleys, for example, are formed by entirely different forces.
formation of a u shaped valley happens over geologic time meaning not during a humans lifespan. It can take anywhere between 10,000 and 100,000 years for a v shaped valley to be carved into a u shaped valley.... As the ice melts and retreats the valley is left with very steep sides and a wide flat floor.
