The water cycle
The water cycle is also known as the hydrological cycle. It describes how water moves on, above, or just below the surface of our planet.

Water molecules move between various locations - such as rivers, oceans and the atmosphere - by specific processes. Water can change state.

The stages
Evaporation
Energy from the Sun heats the Earth’s surface and water evaporates from oceans, rivers and lakes. The warm air rises, carrying water vapour with it.

Transpiration
Transpiration from plants releases water vapour into the air.

Condensation
The moist air cools down as it rises. Water vapour condenses back into liquid water, and this condensation process produces clouds.

Precipitation
As the water droplets in the cloud get bigger and heavier, they begin to fall as rain, snow and sleet. This is called precipitation (it is not the same as precipitation in Chemistry).
