What 2 water sources to people in NJ use for drinking and agriculture? What human activities use the most water? Trace water through the water cycle; Know all key water cycle processes (evaporation; condensation; precipitation; run off; infiltration; ground water; transpiration; respiration) What s a watershed? Define and give an example of permeable and impermeable rock. Define an aquifer. What rock types make good aquifers? From Class Activities and EdPuzzles How does development /urbanization affect water quality of reservoirs? How does development/urbanization affect flooding? How does development/urbanization affect ground water supplies? Give examples of impervious surfaces and how they influence run off and infiltration. Define and give examples of point-source and non-point source pollution. Give examples of how pollution enters our drinking water (ground water and reservoirs) Describe some effects of specific pollutants on lakes or ground water. What problems do these pollutants cause. Describe human activities that use a lot of water. Identify actions that could reduce wasteful water use in farming and residential homes.
