To get a good understanding of this, one needs to know just what is a cloud. A cloud is an area where very tiny water droplets have formed via condensation of water vapor in the air. In most cases, a cloud marks where air has risen by some mechanism to a point high enough to cause condensation. Now the water droplets are very light, and thus can be held up in the atmosphere by this rising air. Indeed, if the air continues to rise and there is sufficient moisture, you get a very tall cloud which will likely produce some form of precipitation.

Good question. I just answered the same question a few days ago. Cloud droplets in a completely still atmosphere would fall to the earth under gravity, although while falling they would evaporate. Even in the real atmosphere with winds clouds are continually dissipating and forming at the same time. Over mountains there is a lens shaped cloud called a lenticular cloud in which the front of the cloud towards the east, the leeside, is dissipating while the rear of the cloud, the windward side, is forming. While the cloud looks as if it is remaining still the winds at that level may be 100 mph or greater.

As long as the cloud and the air that it is made up of is warmer than the outside air around it, the cloud floats.On the other hand, if the tiny water droplets in a cloud combine together to grow until they are heavy enough to fall,they reach the ground as rain.

well technically they do, but thats called fog, or precipitation. the reason the could in the sky dont fall is because the lower section of the atmosphere is too dense for the clouds to pass through

they do.
fog is just low lying clouds. clouds stay up there because they are made of water vapor and salt and dust. water vapor can stay in the air without falling. also they are constently carried by winds that move as fast as 1000 mph in a jet stream

Clouds don't fall but their contents do. The rain is basically the cloud. The cloud is made of the rain. DUH!!!
