Water Cycle Components

Earth's water is always in motion, and the natural water cycle, also known as the hydrologic cycle, describes the continuous movement of water on, above, and below the surface of the Earth. Water is always changing states between liquid, vapor, and ice, with these processes happening in the blink of an eye and over millions of years.

O Ciclo d’água, The water cycle, Portuguese

O Ciclo d’água, The natural water cycle, Portuguese

O ciclo da água, também comumente conhecido como ciclo hidrológico, descreve a existência e o movimento contínuo da água sobre, dentro e acima da Terra. A água da Terra está sempre em movimento e sempre mudando de estado, de liquido para vapor, depois para gelo e novamente de volta para seu estado inicial. O ciclo da água tem...

Precipitation and the Water Cycle

The air is full of water, even if you can't see it. Higher in the sky where it is colder than at the land surface, invisible water vapor condenses into tiny liquid water droplets—clouds. When the cloud droplets combine to form heavier cloud drops which can no longer "float" in the surrounding air, it can start to rain, snow, and hail... all forms of precipitation, the superhighway moving water...
