Question

Match List-I with List-II. List-I Terminology/device: A. Tensiometer, B. Osmotic potential, C. Static water level, D. Contour. List-II Detail: I. Portion of water potential that results from the solute present in the soil system, II. The level at which the water stands in a well before pumping starts, III. Line joining equal elevation point of the field, IV. Soil moisture content.

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

Hint:

A contour line joins points of equal elevation, while static water level is measured before pumping starts.

Answer 1

The Correct Option is D

Concept:
This matching question is based on soil water and field survey terminology.

Step 1: Tensiometer.
Tensiometer is used in relation to soil moisture condition. \[ A\rightarrow IV \]

Step 2: Osmotic potential.
Osmotic potential is the part of water potential due to solutes present in the soil solution. \[ B\rightarrow I \]

Step 3: Static water level.
Static water level is the level at which water stands in a well before pumping starts. \[ C\rightarrow II \]

Step 4: Contour.
Contour is a line joining points of equal elevation. \[ D\rightarrow III \] Therefore: \[ A-IV,\ B-I,\ C-II,\ D-III \] \[ \therefore \text{Correct Answer is (D)} \]
