clouds r made up of water vapor. water vapors r lighter than air. so they rise up. far above the surface the temperature is very low. so the water vapor condenses into water droplets. when they become heavy, they fall down as rain.

Very good question. In a perfectly still atmosphere cloud droplets would fall and evaporate due to gravity. What actually happens in real clouds is that some droplets do fall and evaporate while others are formed when air is lifted and cooled. A cloud is always changing. It is like a supermarket where there are always roughly the same number of people in the market while some are leaving and new people are arriving.

One cloud that forms over mountains, a so called a lenticular cloud because it has the shape of a lens stands motionless over the mountain top while the lee edge is always evaporating and the windward edge is always forming.

I hope this gives you somewhat of an idea as to what is happening.

In 2 easy sentences and not an essay of numbers and climate innovations from another website like different answerer's gave: The clouds are the real of increasing air which extends added down decrease than the cloud and as a result the cloud is in a fashion already on the floor and would't fall. additionally, if the cloud have been to someway fall from loss of increasing air decrease than it, the descent could heat it and evaporate it in maximum circumstances.

Clouds form in rising air. As the air rises it cools and water vapour (which is an invisible gas) condenses to form minute water droplets. These droplets are so small it takes many tens of thousands to make a raindrop. You see similar droplets in fog. The droplets are so small that their weight cannot counteract the rising air and the continue rising. The accumulations of these droplets are clouds.

If the air stops rising, the droplets fall, warm up and evaporate and the cloud disappears.

As long as the cloud and the air that it is made up of is warmer(hence less dense and lighter) than the outside air around it,the cloud floats due to buoyancy.Rain,snow or hail occur when water droplets(or ice crystals) in a cloud grow large and heavy enough to fall to earth.

Water from sea evapourates to give vapours. These vapours being hot rise up and form clouds. Clouds are formed from hot vapours, therefore they donot fall.( Vapours are hot.)
