Question

Humidity is

• A. The amount of air present in any region.
• B. The amount of any liquid present in air.
• C. The amount of elements and compound present in air.
• D. The amount of water vapour present in air.

Answer 1

Answer: (D)

The amount of water vapour present in the atmosphere is known as humidity. The measure of the water vapour present in the atmosphere as compared to vapour content at saturation levels is known as relative humidity. The formation of clouds and rain occurs only at 100% relative humidity and not near the surface. The rising and cooling air forms clouds and increases humidity. The fall of precipitation from the clouds occurs into layers with lower humidity.

Thus, the correct answer is option C.
