Question
Consider the following statements:
Choose the correct statement/s from the codes given below:
- A valley that has been formed by glacial erosion has characteristic V-shaped with very steep sides.
- After the ice melted, a tributary valley ‘hangs’ above the main valley so that its stream plunges down a waterfall.
Choose the correct statement/s from the codes given below:
Answer: Option D
Answer: (d)
A valley that has been formed by glacial erosion has characteristic U-shaped with a wide, flat floor and very steep sides. In glacial erosion, the main valley is eroded much more rapidly than the tributary valley as it contains a much larger glacier.
After the ice has melted a tributary valley, therefore, ‘hangs’ above the main valley so that its stream plunges down as waterfall. Such tributary valleys are called a hanging valley.
