Question

The water vapour that enters the air to form clouds in the sky is obtained by which of the following process?

• A. Condensation
• B. Evaporation
• C. Precipitation
• D. None of the above

Answer 1

The correct option is B Evaporation

• Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase.
• By the process of evaporation, the water vapour enters into the air to form clouds in the sky.
• The water vapour in the air condenses to form tiny water droplets which are the basis of clouds.
• Hence the process by which water vapour enters into the air to form clouds in the sky is Evaporation.
• So, the correct answer is option B.
