Question

Match List-I with List-II

List-I (Parameter) & List-II (Unit)
(A) Relative Humidity & (I) Okta
(B) Temperature & (II) km/hr
(C) Wind Speed & (III) $^\circ$C
(D) Cloud Cover & (IV) %

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

Hint:

Remember that "Okta" is a unique meteorological unit used exclusively to measure cloud cover (ranging from 0 to 8). Matching (D) to (I) immediately leads you to the correct option.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Agricultural meteorology involves measuring various atmospheric and climatic parameters.
Each meteorological parameter is recorded in standardized units of measurement.

Step 3: Detailed Explanation:
Let us match each meteorological parameter in List-I with its standard unit in List-II:
- (A) Relative Humidity $\rightarrow$ % (IV): Relative humidity is the ratio of the actual water vapor pressure to the saturation water vapor pressure at a given temperature, expressed as a percentage (%).
- (B) Temperature $\rightarrow$ $^\circ$C (III): Temperature, representing the degree of hotness or coldness of the atmosphere, is standardly recorded in degrees Celsius ($^\circ\text{C}$).
- (C) Wind Speed $\rightarrow$ km/hr (II): Wind speed, representing the rate of horizontal air movement, is measured using an anemometer and expressed in kilometers per hour (km/hr) or meters per second (m/s).
- (D) Cloud Cover $\rightarrow$ Okta (I): Cloud cover represents the fraction of the sky covered by clouds. It is measured visually in Oktas, where 0 Okta represents a completely clear sky and 8 Oktas represents a completely overcast sky.
This results in the sequence: (A)-(IV), (B)-(III), (C)-(II), (D)-(I).
This matches Option (B).

Step 4: Final Answer:
The correct matching sequence is (A) - (IV), (B) - (III), (C) - (II), (D) - (I).
