Question

Identify the true statements regarding the middle course of a river.

1. The river's velocity is significantly reduced, leading to substantial deposition.
2. The valley becomes broader, and the river banks are more stable.
3. The river continues to transport sand, silt, and mud in suspension.
4. Erosion is less pronounced compared to the mountain course due to lower water velocity.

• A. ii, iii, iv
• B. iii, iv
• C. All
• D. iv only

Answer 1

Answer:

A. ii, iii, iv

THE MIDDLE COURSE

• The middle course of the river occurs over the foothill belt where the velocity or water is comparatively less which moves a little slowly.

• The waters are still fast enough to transport sand, silt and mud in suspension, and to roll pebbles along its bed.

• In this part of the river course, the valley is broad with stable sides, so that the river cannot erode the land, as much as it does in the mountain course.
