UPSC MCQ: Physical Geography- 2 - Question 9

  River rejuvenation can occur due to:

1. Uplift of land over which the river is flowing.

2. Rise in sea-level.

Which of the statements given above is/are correct?

Detailed Solution for UPSC MCQ: Physical Geography- 2 - Question 9

River rejuvenation involves a renewed period of vertical erosion to achieve a new and lower base level. Rejuvenation occurs when the river’s base level falls (i.e. when sea level falls). This can be a consequence of either a fall in the amount of sea water or the land rising. Uplift of land over which the river is flowing steepens the slope so that active down cutting is renewed. A fall in sea-level (and not rise ) causes river rejuvenation. A fall in sea level leaves the flood plain at an increased altitude above the sea level. The river with its renewed vigour cuts into the former flood plain, leaving behind terraces on both sides of the river
