Step-by-step explanation:
The "water cycle" is also known as "hydrologic cycle." It replenishes the water on Earth through a cycle, which is essential for maintaining life and balance on Earth.
The "Sun" plays a vital role in the water cycle process. It fuels it and makes the different processes possible. For example, it allows water to evaporate from the different bodies of water like the rivers, lakes, streams and so on. Heat is being transferred from the Sun to the Earth through radiation, and this allows the liquid state of matter on Earth to change to its gaseous state.
