Water In The Atmosphere
Question
Wired Faculty App

Distinguish between Cloud and Fog.

Answer

i. Cloud : It is a mass of small water drops or the ice crystals formed by the condensation of water vapour in the free air at considerable heights above the earth’s surface. They are mostly formed in the upper regions of the atmosphere.


ii. Fog: When the temperature of an airmass containing a large amount of water vapour falls all of a sudden, condensation takes place within itself on fine dust particles. So fog is a cloud with its base near to the ground.
