cloud formation

Cloud formation occurs when warm, moist air rises and cools in the atmosphere. As the air cools, the water vapor it contains reaches its dew point—the temperature at which it condenses into tiny water droplets or ice crystals. These droplets group together around tiny particles called condensation nuclei, such as dust or pollution. When enough droplets form, they create visible clouds. This process is driven by factors like temperature differences, air pressure, and humidity, and is essential for the water cycle, leading to precipitation and redistribution of water across the planet.
