Water on Earth is in the water cycle. Evaporation, condensation.

The process responsible for the production of water on Earth is known as the water cycle or the hydrologic cycle. Here's an explanation of how this process works:
1. Evaporation: Water from oceans, lakes, rivers, and other water bodies is heated by the Sun, causing it to change from a liquid state to a gaseous state (water vapor). This process is called evaporation.
2. Transpiration: Plants and trees also release water vapor through tiny openings in their leaves called stomata. This process is known as transpiration.
3. Condensation: As the warm water vapor rises into the atmosphere, it encounters cooler air, causing it to condense back into liquid droplets. These droplets gather together to form clouds.
4. Precipitation: When the water droplets in the clouds become large enough, they fall back to the Earth's surface in the form of precipitation, such as rain, snow, sleet, or hail.
5. Runoff: Precipitation that reaches the Earth's surface can flow over the land as runoff, eventually making its way into streams, rivers, and oceans. Some of it also seeps into the ground, replenishing underground water sources (aquifers).
6. Collection: Water that reaches the oceans due to runoff or directly from precipitation collects in large bodies of water, which then completes the cycle and begins the process of evaporation again.
Overall, the water cycle is a continuous process that redistributes water on Earth, ensuring a constant supply of fresh water for various ecosystems and human use.
