1. (9.1) Create a labeled diagram to illustrate how CFCs interact with ozone (03) in the stratosphere. Identify 3anthropogenic sources of CFCs. Are CFCs currently still used in these products? Identify 1 natural cause ofstratospheric ozone depletion. Identify 3 other ozone depleting chemicals. When does the ozone layer typicallythin out over the Antarctic? What is the importance of stratospheric ozone to human health?2. (9.2) Create a chart (include appropriate headings). List, identify advantages and disadvantages for eachsubstitute for CFCs: HCFCs, HFC, and HC. When will stratospheric ozone depletion be reversed? Why will ittake so long?3.4.(9.3) Create a labeled diagram to illustrate the natural greenhouse effect. What effect does the naturalgreenhouse effect have on Earth's climate? What would Earth be like without the natural greenhouse effect?(9.3) Create a chart (include appropriate headings). List, identify at least 3 sources of each GHG, determine if thesource is anthropogenic or naturally occurring, and identify 3 measures to reduce each GHG: CO2, CH4, H₂O,N₂O, and CFCs. List the GHGs in order or least to most global warming potential (GWP).5. (9.3) Create a labeled graph of the Keeling Curve (label the axes and include numbers and units). Identify atleast 4 provisions of both the Montreal Protocol and the Kyoto Protocol. Which one did the US NOT sign andratify and why?6. (9.4) Create a chart (include appropriate headings). Identify and explain how each environmental problem isaffected by increases in GHGS: rising global temperatures, rising sea levels, melting ice sheets, oceanwater expansion, spread of emergent infectious disease. Include in your chart how each problem is related tochanges in population dynamics and the threats to human health.7. (9.5) Create a labeled graph that shows the relationship between carbon dioxide levels and time (last 800,000years. Label the 4 ice ages that would have occurred during that time period. Explain the causes of Earth'snatural climate change. What is the implied relationship between CO₂ level and atmospheric temperature?8. (9.5) Create a chart (include appropriate headings). List, and describe effects of climate change on each:threatened ecosystems, extreme weather events, coral die-off, increased coastal flooding, loss of barrierislands, change in atmospheric currents (Hadley cells and Jet Stream), reduced crop yields, ecologicalrange.9. (9.6) Create a chart (include appropriate headings). List and identify the effect of a warming ocean on marinehabitat loss, metabolic / reproductive changes, and corals. What happens when corals bleach and can coralbleaching be reversed?10. (9.7) Create labeled diagram that illustrates how CO₂ in the atmosphere leads to a decrease in oceanic pH.Provide the balanced chemical equation showing the conversion of CO₂ to carbonic acid. Identify three primaryanthropogenic activities to lead to increased CO₂ concentration in the atmosphere and ultimately the ocean.Describe the effect of an acidic ocean on corals.11. (9.8) Create a chart (include appropriate headings.) Provide 3 examples of invasive species, at least 3characteristics of invasive species, and how to control each species that you listed. Why are invasive speciesconsidered pests?12. (9.9) Create a chart (include appropriate headings). Provide and explain 4 factors that threaten species withextinction, provide and explain 4 factors that could reduce species' extinction, provide and explain 4 strategies (2are laws) that can protect species.13. (9.10) Create a chart (include appropriate headings). List, describe, create a sketch, and propose a reasonablesolution (other than banning) for mitigating each anthropogenic activity: Habitat destruction, invasive species,population growth, pollution, climate change, over exploitation, habitat fragmentation, and domesticationof species.14. (9.5) Draw and label a diagram to explain the albedo effect. How does the albedo effect influence climatechange? Explain how this is related to the positive feedback loop of melting sea ice.
