Geothermal energy, the heat within the Earth, can be used to generate electricity. Chapter 12 Air Key Terms air pollution primary pollutant secondary pollutant smog temperature inversion Summaries Primary pollutants are pollutants put directly in the air by human activity. Secondary pollutants are formed when a primary pollutant comes into contact with other primary pollutants or with naturally occurring substances and a chemical reaction takes place. Most air pollution comes from vehicles and industry. Air pollution that hangs over cities and reduces visibility is called smog. Be able to Name five primary air pollutants, and give sources for each. Name the two major sources of air pollution in urban areas. Describe the way in which smog forms. Explain the way in which a thermal inversion traps air pollution. 12.3 Acid Precipitation Key Term acid precipitation Summaries Acid precipitation is precipitation such as rain, sleet, or snow that contains a high concentration of acids. Acid shock occurs when a sudden influx of acidic water enters a lake or stream and causes a rapid change in pH that harms aquatic life. Pollutants released in one geographical area may fall to the ground hundreds of kilometers away as acid precipitation—sometimes in another country Be able to Explain the causes of acid precipitation.
