Question

38. Mention the significance of water vapour in atmosphere.

Answer 1

Significance of water vapour:

• Water vapour is the gaseous state of water. The importance of water vapour in the atmosphere is that it aids in the water cycle process. Water evaporates and turns into water vapour as a result of evaporation. When water vapour rises in the atmosphere, it combines with dust particles and other gases to produce clouds.
• Water vapour is extremely important in forming the moisture supply for fog, clouds and precipitation.
• It plays a vital role in the radiative balance.
• It transports latent heat and contributes to absorption and emission.
• For the growth of plants, presence of water vapour is essential.
