Chapter 14 Key Terms Rubenstein

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
