TermDefinition
atmosphere the mixture of gases that surround earth
ozone a form of oxygen that has three oxygen atoms in each molecule instead of usual two it is a toxic form of oxygen
air polluition a change to the atmosphere
greenhouse effect The phenomenon whereby the earth's atmosphere traps solar radiation, caused by the presence in the atmosphere of gases such as carbon dioxide, water vapor, and methane.
global warming An increase in the average temperature of the earth's atmosphere, especially a sustained increase sufficient to cause climatic change.
altitude height above sea level or the earth's surface
troposhere The lowest layer of the atmosphere, in which temerature decreases at a constant rate as altitude increases
stratosphere the layer of the atmoshere that is above the troposhere and in which temperature increases as altitude increases
mesosphere the layer of the atmosphere between the stratosphere and thermosphere in which temp decreases as altitude increases
thermosphere Upper most layer of Earth's atmosphere; has two layers ionosphere and exosphere
Exosphere the outermost (top) layer of Earth's atmosphere, from the top of the thermosphere to where the atmosphere merges into outer space
Ionosphere "Charged particles" disrupt AM radio signals, especially at night.
acid rain rainfall containing acids formed whe certain pollutants combine with water vapor in the air

emission the production and discharge of something, especially gas or radiation.
photochemical smog Air pollution produced by the action of sunlight on hydrocarbons, nitrogen oxides, and other pollutants.
temperature inversion condition in which the temperature of the atmosphere increases with altitude in contrast to the normal decrease with altitude. When temperature inversion occurs, cold air underlies warmer air at higher altitudes.
chlorfluorocarbon any of a class of compounds of carbon, hydrogen, chlorine, and fluorine, typically gases used in refrigerants and aerosol propellants
