sulfur oxides acid precipitation — carbon oxides corrosion of metal — hydrocarbons reduced visibility — nitrogen oxides blocks UV radiation — particulate matter production of photochemical smog — Chapter 21: Regional and Global Atmospheric Changes of the following are greenhouse gasses? Mark all that apply carbon dioxide methane water vapor chlorofluorocarbons sulfur oxide The greenhouse effect occurs because: greenhouse gases released interact chemically to produce excess heat. there are too many greenhouses scattered across the Earth's surface. carbon dioxide and other trace gases trap infrared radiation in the Earth's atmosphere. sulfur emissions from smokestacks and volcanoes continue to occur. the gases produced by human activities allow significantly more heat to pass out of the Earth's atmosphere. Chapter 22: Water Pollution One major problem with sewage is that it adds which of the following to water? sodium chloride and dissolved oxygen carbon dioxide and nitrogen nitrogen and phosphorus human wastes and heavy metals soil and microorganisms Chapter 23: The Pesticide Dilemma One benefit of using a machine like the "bug vac" to remove pests from crop plants is: it targets specific pest species. one treatment per season is sufficient for pest control. it is safer for farm workers than pesticides. it is much cheaper to use than pesticides. All of the above.
