A gas that absorbs ultraviolet radiation, found in the stratosphere, a zone between 15 and 50 km above Earth's surface. | Ozone |
A gas used as a solvent, a propellant in aerosols refrigerant and in plastic foams and fire extinguishers | Chlorofluorocarbon |
An atmospheric condition formed through a combination of weather conditions and pollution especially from motor vehicles emissions | Photochemical smog |
Concentration of trace substances, such as carbon monoxide, sulfur dioxide, nitrogen oxides, hydrocarbons, and solid particles, at a greater level that occurs in average air. | Air pollution |
Rapid diffusion of new agricultural technology, especially new high-yield seeds and fertilizers. | Green revolution |
Power supplied by machines | Inanimate power |
A nuclear power plant that creates its own fuel from plutonium. | Breeder reactor |
A place to deposit solid waste, where a layer of earth is bulldozed over garbage each day to reduce emission of gasses and odors from the decaying trash, to minimize fires and to dicourage vermin. | Sanitary landfill |
Conversion of sulfur oxides and nitrogen oxides to acids that return to earth as rain,snow, or fog. | Acid precipitation |
Energy from steam or hot water produced from hot or molten underground rocks. | Geothermal energy |
Fuel that derives from plant material and animal waste | Biomass fuel |
Amount of oxygen required by aquatic bacteria to decompose a given load of organic waste;a measure of water pollution | Biochemical oxygen demand |
A substance in the environment that is useful to people, is economically and technologically feasible to access, and is socially acceptable to use. | Resource |
Farming methods that preserve long-term productivity of land and minimize pollution, typically by rotating soil- restoring crops with cash crops and reducing in-puts of fertilizer and pesticides. | Sustainable agriculture |
The level of development that can be maintained in a country without depleting resources to the extent that future generations will be unable to achieve a comparable level of development. | Sustainable development |
Addition of more waste than a resource can accommodate. | Pollution |
Power supplied by people or animals. | Animate power |
The amount of energy in deposits not yet identified but thought to exist. | Potential reserve |
A resource that has a theoretically unlimited supply and is not depleted when used by humans. | Renewable energy |
Particles from a nuclear reaction that emits radiation | Radioactive waste |
Power generated by moving water. | Hydroelectric power |
The amount of a resource remaining in discovered deposits. | Proven reserve |
A source of energy that is a finite supply capable of being exhausted. | Nonrenewable energy |
Sulfur oxides and nitrogen oxides, emitted by burning fossil fuels, enter the atmosphere-where they combine with oxygen and water to form sulfuric acid and nitric acid-and return to Earth's Surface | Acid deposition |
Solar energy system that collects energy through the use of mechanical devices like photovoltaic cells or flat plate collectors. | Active solar energy systems |
Anticipated increase in Earth's temperature, caused by carbon dioxide trapping some of the radiation emitted by the surface. | Greenhouse effect |
Degradation of land, especially in semiarid areas, primarily because of human actions like excessive crop planting, animal grazing, and tree cutting. | Desertification |
Solar energy cells, usually made from silicon that collect solar rays. | Photovoltaic cell |
Solar energy that collects energy without the use of mechanical devices. | Passive solar energy systems |
The splitting of an atomic nucleus to release energy. | Fission |
