Condensation is the process where water vapor in the air cools down and changes into liquid water. This happens when warm, moist air rises and encounters cooler temperatures, causing the water vapor to lose energy. As a result, tiny droplets of water form, which can be seen on surfaces like grass or windows, especially in the morning or after a warm day. This process is essential in the water cycle, as it contributes to the formation of clouds. When enough water vapor condenses in the atmosphere, it can lead to precipitation, such as rain or snow, replenishing water sources on Earth.
