Current Affairs Prelims Question

When the temperature of an air mass, containing a large quantity of water vapour, falls all of a sudden, condensation takes place within itself on fine dust particles. So, the fog is a cloud with its base at or very near to the ground.
The only difference between mist and fog is that mist contains more moisture than fog. In mist, each nuclei contains a thicker layer of moisture.
Mists are frequent over mountains, as the rising warm air up the slopes meets a cold surface. Fogs are drier than mist and they are prevalent where warm currents of air come in contact with cold currents. Fogs are mini-clouds, in which condensation takes place around nuclei provided by dust, smoke and the salt particles.
