Answer:
The water cycle.
Explanation:
The sun drives the movement of water through a process called the water cycle. In this process, water is evaporated from the sun's heat that reaches Earth. This water rises into the atmosphere in the for of water vapor. This water vapor then collects in the atmosphere along with other particles such as fine dust. This water then precipitates back onto the Earth. Presumably, the water precipitation may fall onto a land formation and integrate back into the ecosystem in the form of ground water or join a steam/river and end up in a lake or the ocean. The water then continues this cycle.
