The process by which water vapor turns into liquid is called condensation. This happens when water vapor in the air cools down and loses energy, causing it to revert to its liquid state. Condensation is an important part of the water cycle and contributes significantly to weather phenomena such as dew formation and cloud development. When warm air containing water vapor rises, it cools at higher altitudes, leading to condensation and the creation of clouds. Once the droplets become heavy enough, they fall to the ground as precipitation, completing the cycle.
