| 9227626099 | emission | the production and discharge of something, especially gas or radiation. |  | 0 |
| 9227626100 | Fossil Fuels | a natural fuel such as coal or gas, formed in the geological past from the remains of living organisms. |  | 1 |
| 9227626101 | Combustion | the process of burning something. |  | 2 |
| 9227626102 | Primary pollutant | A primary pollutant is an air pollutant emitted directly from a source. |  | 3 |
| 9227626103 | Secondary pollutant | A secondary pollutant is not directly emitted as such, but forms when other pollutants (primary pollutants) react in the atmosphere. | | 4 |
| 9227626104 | Catalytic converter | exhaust emission control device that converts toxic gases and pollutants in exhaust gas from an internal combustion engine to less toxic pollutants by catalyzing a redox reaction. |  | 5 |
| 9227626105 | Scrubber | an apparatus using water or a solution for purifying gases or vapors. |  | 6 |
| 9227626106 | Smog | fog or haze combined with smoke and other atmospheric pollutants. |  | 7 |
| 9227626107 | Carbon Cycle | the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth |  | 8 |
| 9227626108 | Carbon Footprint | the amount of carbon dioxide and other carbon compounds emitted due to the consumption of fossil fuels by a particular person, |  | 9 |
| 9227626109 | Acid precipitation | Any form of precipitation, including rain, snow, hail, fog, or dew, that is high in acid pollutants, especially sulfuric and nitric acid. Acid precipitation has a pH of less than 5.6 (the normal acidity of unpolluted atmospheric water) and is often less than pH 5.0. Also called acid rain. |  | 10 |
| 9227626110 | MPG | how many miles of gas you can get per gallon on your car |  | 11 |
| 9227626111 | Clean Air Act | The Clean Air Act is a United States federal law designed to control air pollution on a national level. It is one of the United States' first and most influential modern environmental laws, and one of the most comprehensive air quality laws in the world. |  | 12 |
| 9227626112 | Thermal Inversion | . a reversal of the normal decrease of air temperature with altitude, or of water temperature with depth. |  | 13 |
| 9227626113 | Particulate Matter | is the sum of all solid and liquid particles suspended in air many of which are hazardous. This complex mixture includes both organic and inorganic particles, such as dust, pollen, soot, smoke, and liquid droplets. |  | 14 |
| 9227626114 | Hydrocarbons | a compound of hydrogen and carbon, such as any of those that are the chief components of petroleum and natural gas. |  | 15 |
| 9227626115 | carbon dioxide | a colorless, odorless gas produced by burning carbon and organic compounds and by respiration. It is naturally present in air (about 0.03 percent) and is absorbed by plants in photosynthesis |  | 16 |
| 9227626116 | carbon monoxide | Carbon monoxide is a colorless, odorless, and tasteless gas that is slightly less dense than air. It is toxic to hemoglobic animals when encountered in concentrations above about 35 ppm |  | 17 |
| 9227626117 | AQI | is a number used by government agencies to communicate to the public how polluted the air currently is or how polluted it is forecast to become. As the AQI increases, an increasingly large percentage of the population is likely to experience increasingly severe adverse health effects |  | 18 |
| 9227626118 | Acid Shock | s a number used by government agencies to communicate to the public how polluted the air currently is or how polluted it is forecast to become. As the AQI increases, an increasingly large percentage of the population is likely to experience increasingly severe adverse health effects | 19 |
