what is the importance of dust particles in cloud formation?

Answer 1

Dust particles serve as cloud condensation nuclei. Usually, dust is thought of as insoluble in water but dust can as a be a nucleus for the water droplets.

Answer 2

The water in the atmosphere is in the form of an invisible gas called water vapour.Cloud forms when warm ,humid air rises,expands and cools.Cool air can not hold as much water vapour as warm air.So,condensation of water vapour starts.Water requires a non-gaseous surface to become liquid from a vapour stage.In the atmosphere,this surface presents itself as a tiny solid or liquid particles called cloud condensation nuclei.Dust particles,particles of salt,droplets of sulphuric acid,smoke etc are some of the condensation nuclei.So,water vapour condenses on these dust particles to become water droplets .Millions of such droplets come together to form clouds.So,dust particles are necessary for the formation of clouds.

Answer 3

Particles suspended in air act as sites on which water can condense and thus play a principal role in the water cycle and the formation of clouds that result in rain.

Answer 4

i dont know if I understand your question, but clouds are most made up of gases(h20), dust and other particles are rise into the atmosphere along with the water when it evaporates, the dust particles in the air can linger long after the cloud dissipates and form part of the ozone.
