How and why do clouds form?

Question

lol Rain! How could I forget that grrrrrrr

Answer 1

Clouds form when upward flowing air, which cools from expansion, can no longer contain all of the water vapor it holds. Some of the vapor condenses into cloud droplets (or ice crystals, if the air is cold enough), forming a cloud. (Water vapor is invisible…..cloud droplets are visible). The cloud then has two choices…it can either re-evaporate into water vapor, or the cloud particles can combine together to form precipitation, which then fall to the ground. For the average precipitation system, about one-half of the water will grow large enough to fall to the ground as precipitation, while the other half will remain as small droplets and eventually re-evaporate into water vapor.

Answer 2

Clouds form part of the weather cycle- warm air/high pressure over the sea makes for evaporation, this creates steam, steam form clouds when they are carried by a cool wind inland, low pressure breaks the clouds down to form rain.
Hope that helps- although I might have missed a stage out, its been about 20 years since I have done basic geographics.

Answer 3

Clouds form due to convection.When air having enough moisture is forced to rise,it is being continuously cooled until a level is reached where it can no longer hold the excess moisture thereby leading to condensation of water vapour into water droplets.Many such water droplets form the clouds.
The condensation of water vapour into water droplets requires condensation nuclei.The atmosphere usually has sufficient condensation nuclei in the form of dust particles,salt particles and droplets of sulphuric acid.So when the air reaches the dew point temperature condensation of water vapour takes place.Making use of the condensation nuclei the water vapour becomes water droplets which in turn form the clouds.

Answer 4

they form by prticles and why if there were no clouds no clouds no rain no rain no water no water no life no life no erath no earth what the heck just ur nevwer were ganna be born
