A natural force exerted on a body toward the earth's surface or between two bodies. Gravity has a strong effect on how matter interacts. Gravitational attraction depends on the masses of the bodies involved and the distance between them. Centrifugal force caused by the earth's rotation on its axis tends to lessen the force of gravity.

A natural process by which a water body uses microbes, which convert nonliving substances into protoplasm or cells, to purify itself from pollutants.

A naturally occurring fibrous mineral found in certain types of rock formations. The primary use of asbestos was as a fireproofing material, applied to structural steel members in multistory commercial buildings to attain proper fire protection. With its resistance to heat, asbestos was able to keep the building structure from bending and warping if exposed to fire. After widespread use of asbestos, over a 15 to 25 year time span, a pattern of illness gradually began to occur in asbestos workers. Three diseases linked to asbestos exposure are asbestosis, a fibrous scarring of the lungs, lung cancer, and mesothelioma, a cancer of the lining of the chest or abdominal cavity.

A naturally occurring organic compound, of the general empirical formula, C<sub>10</sub>H<sub>16</sub>, biologically built from a naturally occurring "monomer" called isoprene, C<sub>5</sub>H<sub>8</sub>, which is found as a volatile oil in plants. A clearly important--and olfactorily obvious--example is alpha-terpinene found in lemon oil.

A naturally occurring volatile organic compound, it is a component of petroleum and coal and is released by the burning of wood or tobacco. It is also used in moth repellants, dyes and pharmaceuticals. Like other nonmethane hydrocarbons it is oxidized and subsequently it reacts with NO in the atmosphere to produce NO<sub>2</sub>. The NO<sub>2</sub> is photolyzed to produce NO and O. The O then reacts with O<sub>2</sub> to produce ozone.

A painful, disfiguring condition similar to common acne that it caused by people being exposed to high concentrations of PCB's (polychlorinated biphenyls). It is a biological response to the exposure of different types of organochlorine compounds.

A particle that has no rest mass, no electrical charge and whose energy is determined by its electromagnetic wavelength. A photon is considered to be an amount of electromagnetic radiation energy that is proportional to the frequency of that radiation. It may also be considered as a particle of light with energy, hv, where h is Planck's constant and v is the frequency of light.
