• Do you understand the hydrological cycle?
• What is evapotranspiration?
• What is water in the U.S. used for? Internationally? (relative percentages)
• What is an aquifer? Why do I care about its recharge and discharge areas
• What are the pros and cons of ‘additional’ water sources? (groundwater, cloud seeding, dams, diversions, desalination, conservation)
