A cloud is a visible mass of water droplets or ice crystals suspended in the Earth's atmosphere. Clouds form when moist air rises and cools, causing water vapor to condense into tiny droplets or ice crystals around microscopic particles called cloud condensation nuclei.
Clouds can vary in shape, size, and altitude, and are classified based on their appearance and height in the atmosphere.
