It's a multicultural institution that offers 79 bachelorette degree programs, 54 masters and five ...
This radical is a primary pollutant from many sources, the most common and abundant is automobile exhaust. It's importance in the atmosphere is great because it is a catalyst in the destruction of ozone.
Industry:Chemistry; Weather
The transfer of gas to the surface of a water droplet from the bulk atmosphere, and the gas mixing within the droplet.
Industry:Chemistry; Weather
The process of planetary surface plate formation, movement, interaction, and destruction. The consequence of this process is that many regions of the planet are situated near interacting--and slowly moving--plates. The process causes earthquakes such as those along the West Coast of the United States and in Japan.
Industry:Chemistry; Weather
The process by which water is transpired and evaporated from the land and water, condensed in the clouds, and precipitated out onto the earth once again to replenish the water in the bodies of water on the earth.
Industry:Chemistry; Weather
The process of oxidizing living material. This process produces atmospheric particulates as well as the production of greenhouse and reactive tropospheric gases. These gases include CO<sub><sub>2</sub></sub>, CO, NO<sub><sub>x</sub></sub>, CH<sub><sub>4</sub></sub>, CH<sub>3</sub>Cl along with the addition of black carbon. All of these chemical species can be lofted relatively high in the atmosphere due to the convective heating of a fire.

These are hydrocarbons such as ethylene, butane, hexane, propane and, by definition, exclude the first member of that analogous series, CH<sub>4</sub>. Large quantities of NMHCs are emitted from vegetation, the vast majority as isoprene, C<sub>5</sub>H<sub>8</sub>. The natural emission of isoprene is significant compared to that of anthropogenic NMHC.
Industry:Chemistry; Weather
The release of "young" gases into the earth's atmosphere by volcanic activity.
Industry:Chemistry; Weather
This is the lapse rate (the rate of change of the temperature in the gases in the atmosphere along different altitudes) of a mass of moist air as it rises in the atmosphere. This rate begins to slow as the dew point is reached and condensation forms. This rate of cooling goes from 4 degrees C/km all the way to 9 degrees C/km depending on humidity. Contrast with the dry adiabatic lapse rate which is 9. 8 degrees C per km of rise. The saturated lapse rate is always less than the dry rate because the lapse rate (cooling) is less for air that contains water vapor which releases its latent heat as it cools, suppressing the cooling.
Industry:Chemistry; Weather
The total radiant flux received on a unit area of a given real or imaginary surface. Also called the radiant flux density.
Industry:Chemistry; Weather
The unsaturated zone in a soil where chemical processes are at their most active. Its extent is determined partly by the content of the soil water, but it cannot extend beyond the water table, below which voids are completely filled with water.
