Stratospheric Ozone Production
csl.noaa.gov20 Questions: 2010 Update Section I: OZONE IN OUR ATMOSPHERE Stratospheric ozone. Stratospheric ozone is formed naturally by chemical reactions involving solar ultraviolet radiation (sunlight) and oxygen molecules, which make up 21% of the atmosphere. In the first step, solar ultraviolet radiation breaks apart one oxygen molecule (O 2) to produce

forecast.uchicago.eduIn fact, most of the gases in the atmosphere do not absorb or emit IR light at all, because vibrations in their bonds do not create an imbalance in the electrical field. Both O 2 and N 2, the most abundant gases in the atmosphere, are symmetric molecules, made of two identical atoms whose electric fields just cancel each other out.

www.nasa.govan additional factor that destroys ozone. CFCs are molecules made up of chlorine, fluorine and carbon. Because they are extremely stable molecules, CFCs do not react with other chemicals in the lower atmosphere, but exposure to ultraviolet radiation in the stratosphere breaks them apart, releasing chlo-rine atoms.

pwg.gsfc.nasa.govenergy to oxygen and nitrogen molecules, making them excited. When the molecules return to their normal state, they release photons, small bursts of energy in the form of light. When billions of these collisions occur and enough photons are released, the oxygen and nitrogen in the atmosphere emit enough light for the eye to detect them.

Tritium Fact Sheet - Health Physics Society
hps.orgTritium exists throughout our worldwide environment in the atmosphere, ground water, soil, rivers, lakes, streams, and oceans from both natural and man-made production. It is generated naturally in the atmosphere through interactions between nitrogen in the air and radiations originating from outer space, known as cosmic rays.

web.pdx.eduMonomers are atoms or small molecules that bond together to form more complex structures such as polymers. There are four main types of monomer, including sugars, amino acids, fatty acids, and nucleotides. Each of these monomer types play important roles in the existence and development of life, and each one can be synthesized abiotically.
