Any condensed form of water--larger than a single water molecule--that is falling or suspended in the atmosphere; some examples of hydrometeors are snow, fog, cloud or rain. When these particles reach the size of 10-20 micrometers, available water is depleted and a stable cloud is formed.

Any energy source that can be harnessed without the use of burning fossil fuels. Such alternative sources are almost always a renewable energy source such as hydroelectric power, wind power, and solar power.

Any physical body absorbs and emits electromagnetic radiation when its temperature is above absolute zero. Planck's law determines the radiant flux of a body at a specific wavelength. In atmospheric chemistry, the calculation involving the earth's blackbody radiation shows that the earth's surface temperature would be below the freezing point of water if it did not have an atmosphere which absorbed some of the outgoing radiation.

Any substance that causes the eye to tear, redden, and or swell; eye irritant examples include formaldehyde, brombenzyl cyanide, chloroacetophenone, and dichlorodimethyl ether.

Aqueous chemistry under high temperature conditions. In biospheric chemistry, this refers to water whose chemical composition has been altered by deep, hot rock and which tends to come to the surface at fault lines. This creates boiling springs and geysers.

Ar, an element that is a member of the 8A group (Noble Gases) of the periodic table. Argon is represented by the atomic symbol Ar, has an atomic number of 18, and an atomic weight of 39. 948. It is colorless, odorless, and a very inert gas. It comprises about 1% of the Earth's atmosphere.

Asteroids or comets striking the earth; a possible cause of major climate changes and mass extinctions in the Earth's history.

Branch of biology which focuses on the relationships among various species and among the species and their environments. The basic units for study are the species (all the organisms which are capable of interbreeding), population (all of the members of a species occupying a certain geographical area) and community (number of populations interacting within a certain area). The emphasis in environmental science, however, is on the processes of energy flows and nutrient cycles within these communities and ecosystems and involves such ideas as species abundance, biodiversity, complexity, trophic (feeding status) levels, ecological niches, and structure of communities.

C<sub>2</sub>Cl<sub>3</sub>F<sub>3</sub> (CFC-113), a chlorofluorocarbon with a long atmospheric lifetime (~85 years) and the third highest abundance in the Earth's atmosphere (behind CFC-11 and CFC-12). It has been used as a working fluid and blowing agent. Like other stable CFCs, it can and will, however, rise above the troposphere and be photolyzed in the available UV radiation of the upper stratosphere, releasing atomic chlorine (Cl dot) which will ultimately catalytically destroy stratospheric ozone. The Montreal Protocol called for the phase out of CFC-113 by 2010.
