  1. 29. Describe Fall Turnover in a lake by highlighting how and when it occurs and why it is important.

  2. CAUSE Connection/Discussion • FRQ: Environmental conditions in coastal estuaries vary hourly and seasonally. • a. Discuss TWO important causes for the variation in temperature and/or salinity of an estuary. • Be sure to include the connection between each cause and the variation in temperature and/or salinity. Daily Tides Seasonal flow from rivers- snowmelt Storms Seasonal changes in air temp Wind Cloud Cover Drought Daily temp changes day/night Evaporation

  3. b. Discuss TWO roles that the coastal wetlands play that are ecologically important. High biodiversity Nursery Migration/nesting site Filter Reduce flooding Reduce erosion Unique habitat High NPP area

  4. Tourism Property protection Fishing industry Filter Employment Sewage/storm water treatment Agriculture Tidal power Source of Methane gas Cooling for powerplants Aquaculture Aesthetic value c. Discuss TWO roles that the coastal wetlands play that are economically important.

  5. IDENTIFY EXPLAIN • d. Identify and explain TWO specific ways in which humans have had a negative impact on coastal wetlands. Construction/building Industry Housing/agriculture Roads/bridges Dredging Petroleum drilling Overharvest/overfish Dam construction Water diversion Sewage/waste water dumping Boat traffic Invasive species Landfill, illegal dumping Deforestation
