Unit 3: The Water all Around: Understanding the Hydrosphere

Unit 3: The Water all Around: Understanding the Hydrosphere describes the hydrosphere - the sphere composed of water. Evolving along with the atmosphere from gases emitted from the litosphere, water takes many forms. The oceans, the incredible movement of glaciers, and the life-giving movement of surface water across the planet are all addressed. The general concepts in this section are:

• Water: the Ultimate Shape-Shifter (chapter 10),
• Water in Oceans and Seas (chapter 11),
• Water in Rivers, Lakes, and Wetlands (chapter 12), and
• The Cryosphere: Studies in Ice and Snow (chapter 13).
