SMOG ! Start at www.geocities.com/smogchem/smog1.html 1. What is smog? 2. What are the two types of smog? 3. Explain what is necessary for each of the two types of smog. The go to www.chem.wisc.edu/courses/108/108-Fall97/smog.htm 4. Explain two ways that ozone is naturally formed. 5. Why and where is ozone harmful? Not harmful? 6. What are two ways to reduce carbon monoxide emissions from the incomplete combustion of fossil fuels? 7. Write equations to show how nitrogen oxides produce ozone. 8. What are some of the negative effects of ground level ozone? 9. Explain how photochemical smog is created. Include all three components necessary and all appropriate reactions. 10. Explain how industrial smog is created. Now go to http//hk.geocities.com/xavier114fch/03/03b.htm and add this info to question number 9. (include the free radicals here!) Now go to www.ausetute.com.au/photsmog.html 11. Show how NO2 gas can both create and destroy ozone. 12. Go to link at bottom of page for “sciencemaster” and explain how volcanic gases that are initially deep within the earth, end up high in the earth’s atmosphere. 13. What are the three most abundant gases released during volcanic eruptions? 14. Approximately how many tones of SO2 a day are released during an eruption? 15. What can be some effects of SO2 being released from a volcano? 16. Compare CO2 emissions from volcanoes with the amount of CO2 released by human activity. Then go to daphne.palomar.edu/calenvironment/smog.htm 17. What happened during a thermal inversion and how is it different from “normal” conditions? 18. What types of conditions might lead to a thermal inversion? 19. Why do thermal inversions decrease air quality? Finally : http://royal.okanagan.bc.ca/mpidwirn/atmosphereandclimate/smog.html 20. Explain how time of day and weather conditions work to form photochemical smog. 21. The summary table is a good one. I’ve printed out a copy for you!
