Water moves through Earth’s environment in a continuous cycle. fresh water salt water water cycle evaporation CLASSZONE.COM VISUALIZATION See how water moves through Earth’s system in the water cycle. condensation precipitation CHAPTER RESOURCES SECTION OUTLINE

Fresh water flows and freezes on Earth. 11.2 Fresh water flows and freezes on Earth. Water on land collects and flows in rivers and lakes. Much of Earth’s fresh water is frozen. divide drainage basin Lake River turnover eutrophication iceberg CHAPTER RESOURCES SECTION OUTLINE

Fresh water flows underground. 11.3 Fresh water flows underground. Water collects and moves beneath the land surface. groundwater permeable Water collects in open spaces in soil, gravel, or rock. impermeable Gravity pulls water down through permeable materials until it reaches an impermeable layer. water table aquifer spring The impermeable layer prevents water from sinking farther down. artesian well CHAPTER RESOURCES CLASSZONE.COM SIMULATION Explore how groundwater fills in aquifers.
