Question

Match List-I with List-II.
{|l|l|} List-I (Process/Practice) & List-II (Title of Process)
(A) A man-made deposit of soil, rock, or other materials, is often used to form an impoundment & (I) Gully erosion
(B) Relatively deep incision of the soil surface caused by concentrated overland runoff & (II) Splash erosion
(C) Small eroding channels are produced by surface runoff & (III) Rill erosion
(D) The dispersal of soil particles resulting from direct raindrop impact on the soil surface & (IV) Embankment

• (A) - (IV), (B) - (I), (C) - (III), (D) - (II)
• (A) - (I), (B) - (II), (C) - (III), (D) - (IV)
• (A) - (I), (B) - (II), (C) - (IV), (D) - (III)
• (A) - (III), (B) - (IV), (C) - (I), (D) - (II)

Hint:

Remember the progressive stages of water erosion in order: Splash erosion $\rightarrow$ Sheet erosion $\rightarrow$ Rill erosion $\rightarrow$ Gully erosion.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Soil conservation and water management involve understanding different stages of soil erosion and the engineering structures used to manage water and soil movement.

Step 2: Detailed Explanation:
Let us analyze and match each process from List-I with its title in List-II:
- (A) A man-made deposit of soil, rock, or other materials to form an impoundment: This describes an engineering barrier constructed to retain water or soil, which is called an Embankment. Therefore, (A) matches with (IV).
- (B) Relatively deep incision of the soil surface caused by concentrated overland runoff: When water flows in concentrated channels, it carves out deep, wide channels that cannot be easily removed by normal tillage operations. This is known as Gully erosion. Therefore, (B) matches with (I).
- (C) Small eroding channels produced by surface runoff: These are small, finger-like micro-channels formed on the soil surface that can be easily smoothed over by normal agricultural tillage. This is called Rill erosion. Therefore, (C) matches with (III).
- (D) The dispersal of soil particles from direct raindrop impact: This is the first stage of water erosion, where the kinetic energy of falling raindrops breaks apart soil aggregates and splashes soil particles. This is called Splash erosion. Therefore, (D) matches with (II).
This yields the matching sequence: (A) - (IV), (B) - (I), (C) - (III), (D) - (II).

Step 3: Final Answer:
The correct match combination is given by option (A).
