Chapter 7, "The Water Cycle," specifically topic 7.1, "Water Reserves and Their Exchanges," discusses the various forms and locations of water on Earth. It explains that water exists in three states: solid, liquid, and gas, and it can be found in oceans, glaciers, groundwater, and the atmosphere. The chapter also delves into the exchanges between these reserves through processes like evaporation, condensation, precipitation, and runoff.
