Question

Match List-I with List-II. List-I Process of water movement: A. Downward movement or entry of water into the soil surface, B. The movement of water through a column of soil, C. Downward and lateral movement of water into the soil, D. Movement of irrigation water from surface into and through the soil. List-II Terminology: I. Seepage, II. Water intake, III. Infiltration, IV. Percolation.

• A. A-I, B-III, C-IV, D-II
• B. A-IV, B-III, C-I, D-II
• C. A-III, B-IV, C-I, D-II
• D. A-III, B-I, C-IV, D-II

Hint:

Infiltration is entry into the soil surface, while percolation is movement through the soil profile.

Answer 1

The Correct Option is C

Concept:
Water movement in soil includes infiltration, percolation, seepage and water intake.

Step 1: Infiltration.
Downward movement or entry of water into the soil surface is infiltration. \[ A\rightarrow III \]

Step 2: Percolation.
Movement of water through a column of soil is percolation. \[ B\rightarrow IV \]

Step 3: Seepage.
Downward and lateral movement of water into soil is seepage. \[ C\rightarrow I \]

Step 4: Water intake.
Movement of irrigation water from surface into and through the soil is water intake. \[ D\rightarrow II \] Therefore: \[ A-III,\ B-IV,\ C-I,\ D-II \] \[ \therefore \text{Correct Answer is (C)} \]
