A visible mass of condensed water vapor suspended in the atmosphere is referred to as a cloud. Clouds form when water vapor rises, cools, and condenses into tiny droplets or ice crystals, depending on the temperature. These droplets cluster together, creating visible formations in the sky. Clouds play a crucial role in the Earth's weather and climate systems, influencing precipitation patterns and temperature. Various types of clouds can indicate different weather conditions, making cloud classification important in meteorology. Understanding cloud formation is vital for predicting weather and studying climate changes.
