Question

9. Both the formation of mist and clouds involve the condensation of water vapor. In which aspect do they differ from each other?

• A. The process of cloud formation takes place in summer, whereas the process of mist formation takes place in winter.
• B. The mist formation takes place in lower layers while cloud formation takes place in the upper layers of the troposphere.
• C. Clouds are suspended in the atmosphere while mist settles down on leaves, walls, etc. on earth's surface.
• D. The water droplets of a cloud have a much lower temperature than that of water droplets of mist.

Answer 1

The correct option is B

The mist formation takes place in lower layers while cloud formation takes place in the upper layers of the troposphere.

Explanation:

• Water vapor along with dust particles is responsible for the formation of clouds, mist, fog, etc.
• Both the formation of mist and clouds involve the condensation of water vapor and occur in the lowermost part of the atmosphere i.e. the troposphere.
• The water vapor that condenses high in the atmosphere is called a cloud.
• The water vapor that condenses close to the earth's surface is called fog or mist.
• Therefore, the mist formation takes place in the lower layers while cloud formation takes place in the upper layers of the troposphere.

Hence the correct answer is option B.
