Condensation is the process where water vapor in the air cools down and changes into liquid water. This occurs when warm, moist air rises and cools, causing the water molecules to come together and form tiny droplets. You can often see this happening on a cold glass of water or on the outside of a bathroom mirror after a hot shower. This process is essential in the water cycle, as it contributes to the formation of clouds and precipitation. When enough water vapor condenses, it can lead to rain, snow, or dew, playing a crucial role in maintaining Earth's ecosystems.
