For example: the pool of water in use, but also through the groundwater recharge, rain and other ways to get added, but time is limited or under certain conditions is limited, such as water pollution, loss of use value, the resource is limited. As can be.
Although the water cycle is infinite, but in a certain period of time and space, the supply of precipitation and water resources is limited. It can be seen that the water resources are the unity of opposites of the infinity of the process and the limitation of the specific amount of recharge
The water on the earth is not static, and the two is in the process of phase change and spatial position, there is a huge water cycle process. All kinds of water bodies can be recovered, renewed and regenerated through the process of cycle and cycle
