Condensation occurs when warm, moist air rises and cools. As the air cools, the water vapor in the air condenses into tiny water droplets. These droplets then fall to the ground as rain, snow, sleet, or hail.

Condensation occurs all over the world, but it is most common in areas with high humidity and warm temperatures. These areas include the tropics, the subtropics, and the eastern United States. Condensation also occurs in mountainous areas, where the air is often cooler and more humid at higher elevations.

The process of condensation is important for the Earth's climate. Condensation releases heat energy into the atmosphere, which helps to keep the planet warm. Condensation also helps to distribute water around the globe, from the oceans to the land.
