Q111 (NDA-I/2024) Geography › World Physical Geography Official Key

Which of the following statements regarding humidity is/are correct ? 1. It is a ratio between the actual amount of water vapour present in the atmosphere and the maximum amount it can hold at a given temperature. 2. When the relative humidity is high, more water evaporates from the skin. 3. Higher the air temperature lower the relative humidity of the air. Select the answer using the code given below :

Result
Your answer: —  Â·  Correct: C
Explanation

The official answer is Option C (1 and 3 only) based on the principles of climatology:

  • Statement 1 is correct: Relative Humidity (RH) is defined as the ratio between the actual amount of water vapour present in the air and the maximum amount (saturation capacity) the air can hold at that specific temperature.
  • Statement 2 is incorrect: When relative humidity is high, the air is near its saturation point, which decreases the rate of evaporation from the skin. This is why we feel more uncomfortable and sweaty in humid conditions.
  • Statement 3 is correct: The water-holding capacity of air increases with temperature. If the absolute amount of moisture remains constant, an increase in air temperature results in a decrease in relative humidity.
