How are clouds formed?
|
|
Water evaporates from land, lakes, and sea and is carried by the air as water vapour. Warm air can hold more water vapour than cold air. As warm air rises and cools, for example over a mountain, the water vapour condenses to water, forming clouds. Eventually, the water falls from the clouds as rain. The rainwater runs back into the rivers and lakes.
