2023年10月19日 · Evaporation is the process of a liquid's surface changing to a gas. In the water cycle, liquid water (in the ocean, lakes, or rivers) evaporates and becomes water vapor. Water vapor surrounds us, as an important part of the air we breathe. Water vapor is also an important greenhouse gas.
Water cycle - Wikipedia
The water cycle (or hydrologic cycle or hydrological cycle) is a biogeochemical cycle that involves the continuous movement of water on, above and below the surface of the Earth. The mass of water on Earth remains fairly constant over time.
