Clouds are made up of tiny water droplets or ice crystals, usually a mixture of both.
Clouds appearing in the sky are valuable for predicting the weather, which is done by deciphering the type of cloud and its features.
Clouds have been broadly classified into three types, on the basis of their location in the sky.
Clouds are a collection of very small drops of water or tiny pieces of ice that are held in the air.
Clouds are formed of water that has evaporated from rivers, lakes, oceans, or moist soil and plants.
Clouds change as parts evaporate in dryer air or they are moved and reshaped by wind and air currents.

Distribution: Worldwide, except Antarctica; common in the tropics.
When tiny particles of pollution in the air (called ?aerosols?) mingle with certain kinds of clouds they change the clouds? properties, making them whiter, more reflective, and longer lasting, which enhances their ability to shade and cool the surface below them.

In rare cases, the updraft associated with the cloud is so powerful that it punches through the tropopause and carries a parcel of cloud into the lower levels of the stratosphere, before losing momentum and falling back.
These clouds grow upward and they can develop into giant cumulonimbus clouds, which are thunderstorm clouds.
This condensation (cloud formation) happens when warm and cold air meet, when warm air rises up the side of a mountain and cools as it rises, and when warm air flows over a colder area, like a cool body of water.
