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.
|A gas used as a solvent, a propellant in aerosols refrigerant and in plastic foams and fire extinguishers
|An atmospheric condition formed through a combination of weather conditions and pollution especially from motor vehicles emissions
|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.
|Rapid diffusion of new agricultural technology, especially new high-yield seeds and fertilizers.
|Power supplied by machines
|A nuclear power plant that creates its own fuel from plutonium.
|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.
|Conversion of sulfur oxides and nitrogen oxides to acids that return to earth as rain,snow, or fog.
|Energy from steam or hot water produced from hot or molten underground rocks.
|Fuel that derives from plant material and animal waste
|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.
|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.
|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.
|Addition of more waste than a resource can accommodate.
|Power supplied by people or animals.
|The amount of energy in deposits not yet identified but thought to exist.
|A resource that has a theoretically unlimited supply and is not depleted when used by humans.
|Particles from a nuclear reaction that emits radiation
|Power generated by moving water.
|The amount of a resource remaining in discovered deposits.
|A source of energy that is a finite supply capable of being exhausted.
|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
|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.
|Degradation of land, especially in semiarid areas, primarily because of human actions like excessive crop planting, animal grazing, and tree cutting.
|Solar energy cells, usually made from silicon that collect solar rays.
|Solar energy that collects energy without the use of mechanical devices.
|Passive solar energy systems
|The splitting of an atomic nucleus to release energy.
