Detailed explanation-1: -The warm, moist air is less dense than the cold air above it, so that warm air rises2. The warm air cools as it comes into contact with the cooler air above. Cold air cannot hold as much moisture as warm air: the vapor has to condense into a liquid. This is the beginning of a cloud.

Detailed explanation-2: -The water and ice particles in the clouds we see are simply too small to feel the effects of gravity. As a result, clouds appear to float on air. Clouds are composed primarily of small water droplets and, if it’s cold enough, ice crystals.

Detailed explanation-3: -Even though a cloud weighs tons, it doesn’t fall on you because the rising air responsible for its formation keeps the cloud floating in the air. The air below the cloud is denser than the cloud, thus the cloud floats on top of the denser air nearer the land surface.

Detailed explanation-4: -Colder clouds are higher in the atmosphere while warmer ones are closer to the surface. Also, warmer clouds can hold more water vapor than colder clouds, making it possible for clouds closer to the surface to become thicker and bigger than higher clouds.

Detailed explanation-5: -Clouds form when moist, warm rising air cools and expands in the atmosphere. The water vapor in the air condenses to form tiny water droplets which are the basis of clouds.
