What is the best reason for calling water vapour a variable atmospheric component?
Answer and explanation
Correct answer: Its amount varies greatly with place and time
Water vapour is called a variable component because its concentration changes markedly from place to place and from season to season. Warm oceans, humid regions and evaporation can produce more vapour, whereas cold or dry regions contain much less. It occurs mainly in the lower atmosphere, not only in the stratosphere, and it is not a permanent gas. Hence option A is correct.
