The Water cycle, also known as the hydrologic cycle or the H₂O cycle, describes 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 but the partitioning of the water into the major reservoirs of ice, fresh water, saline water and atmospheric water is variable depending on a wide range of climatic variables.

The water cycle involves the exchange of energy, which leads to tempurature changes. For instance, when water evaporates, it takes up energy from its surroundings and cools the environment

You have learned all about the water cycle by identifying evaporation, condensation, precipitation, and run-off. Now discuss with a partner the following questions. What did you learn about the water cycle? How does the water move in a circle? What would happen to the water cycle if the sun stopped shining? Can humans run out of water? How?
