APES Unit 7
| Term | Definition |
|---|---|
| Dust and soot are examples of this type of pollutant | Particulate Matter |
| Photochemical smog forms when primary pollutants and secondary pollutants react in the presence of this. | Sunlight |
| These two pollutants contribute the most to acid deposition | nitrogen oxides and sulfur dioxide |
| This occurs when a layer of warm air traps cooler air below it and commonly occurs in this west coast city | thermal inversion of Los Angeles |
| The pollutants commonly targeted by electrostatic precipitators and scrubbers respectively | particulate matter, and sulfur oxides |
| This pollutant reduces the bloods ability to carry oxygen, causing headaches, dizziness, and even death | carbon monoxide |
| Furniture stuffing, paneling, and foam insulation are all sources of this pollutant | Formaldehyde |
| The four most dangerous indoor air pollutants according to the EPA. | asbestos, radon, cigarette smoke, and formaldehyde |
| The criteria for determining if a building is sick | 20%1 or more people complaining of symptoms such as headaches, nausea, fatigue, and coughing2 while in a building3 but feeling better when they leave4 |
| This pollutant comes from the radioactive decay of uranium and its remediation technique | radon and proper ventilation |
| The layer of the atmosphere that contains this helpful ozone | the stratosphere |
| The thinning of the ozone layer is occurring primarily over this continent at this time of year | Antarctica in October/spring |
| Much of the ozone thinning has been caused by this chemical and specifically this element | chlorofluorocarbons (CFCs) and the chlorine molecule |
| Less ozone means increased exposure to this radiation which causes | UVB radiation which causes skin cancer |
| The first meeting to reduce CFC emissions was held in this location and established this agreement | Montreal and the Montreal Protocol |
| The most abundant and variable nonanthropogenic greenhouse gas | water vapor |
| The percent increase in carbon dioxide from 283 ppm in 1790 to 383 ppm in 2007 | 30-38% |
| The greenhouse gas that is a product of anaerobic respiration, livestock gas, and landfills | Methane |
| This makes a greenhouse gas more potent than CO2 | GHG's ability to absorb more heat energy |
| The type of radiation that is absorbed by Earth's surfaces that is re-emitted as this type of radiation | visible light and infrared |
| The region of Earth that will experience the most significant changes in temperature as warming continues | the poles |
| A possible effect of the rapid ice loss in the arctic is the shutdown of this process because of the inundation of melting freshwater | the oceanic conveyor belt |
| Since 1900, the Earth's temperature has risen by about this amount | 0.6-0.8°C? (1°C or 1.5°F is acceptable) |
| The reason that the melting of Earth's ice (glaciers, ice sheets, ice caps) will cause to the further increase in Earth's temperature | the lower albedeo of water compared to ice |
| The reason that infectious tropical diseases are likely to spread to higher latitudes as Earth's average temperature increases | rising temperatures allow disease-carrying mosquitoes to move into new areas |
