The Earth has many reservoirs for storing water. Oceans, lakes, rivers, and streams are natural reservoirs. There are also artificial reservoirs such as tanks that are also efficient reservoirs. Most of the Earth’s water is stored in oceans, but the majority of Earth’s freshwater is stored in glaciers.
The water cycle is a balanced system that is unending. Many processes that are involved in the system help to replenish it including condensation, evaporation, precipitation, and runoff. It is important to appreciate the water cycle, but remember to always conserve water.
