Which process would become difficult without water vapour in the atmosphere?
Answer and explanation
Correct answer: Formation of clouds and rainfall
Water vapour is essential to the atmospheric water cycle. When moist air rises and cools, water vapour condenses into droplets or ice crystals, forming clouds; further condensation and coalescence can produce rainfall. Without water vapour, ordinary cloud and rain formation could not occur. Combustion, nitrogen balance, and most ultraviolet absorption do not depend directly on atmospheric water vapour, so option D is correct.
