The source of water
Water is a colorless and transparent liquid, which is one of the most important, common, and fundamental substances on Earth.
The main source of water is the water cycle process in nature, which means that water on Earth (including oceans, lakes, rivers, groundwater, atmospheric water, etc.) will circulate and flow through processes such as evaporation, rainfall, underground leakage, and river flow, gradually supplementing and updating water resources.
Water is an indispensable resource for both humans and nature. We should pay attention to and protect water resources, develop and utilize them reasonably, establish sustainable water resource management methods, and ensure that future generations can enjoy clean and sufficient water resources.
Water has stable chemical properties and is an inert substance that is not easily reactive with other substances. Therefore, it is used as a solvent in the preparation of many chemical mixtures. The unique properties of water make it widely used in human production, life, and other aspects.
