Question 1
Which process involves the wearing away of the river bed and banks by the load hitting them?
- A) Hydraulic action
- B) Abrasion
- C) Attrition
- D) Solution
Show answer
Answer: Abrasion
Abrasion occurs when large boulders and pebbles carried by the river collide with the bed and banks. This mechanical action gradually erodes the channel, making it deeper and wider over time.

Question 2
What is the name of the steep, rocky drop in a river's course often found in the upper stage?
Show answer
Answer: Waterfall
Waterfalls form where a river flows over a band of hard, resistant rock overlying softer, less resistant rock. As the soft rock erodes faster, it creates a drop, eventually leading to the formation of a plunge pool.

Question 3
Which of the following describes the total volume of water flowing through a channel at a given point?
- A) Velocity
- B) Discharge
- C) Load
- D) Gradient
Show answer
Answer: Discharge
Discharge is measured in cubic metres per second (cumecs). It is calculated by multiplying the cross-sectional area of the river by its average velocity.
