Document Summary
Ensp 101 chapter 17 atmospheric science, air quality, and pollution control. Atmosphere- the thin layers of gases that envelops our planet. Remaining 1% is argon and minute concentrations of water vapor and other gases. Permanent gases: remain at stable concentrations over centuries or millennia. Variable gases: can vary in concentration on short time scales or from place to place as a result of natural processes or human activities.

Contains three-quarters of the atmospheres mass (gravity pulls mass downwards, making air denser closer to the earths surface. Trophic air gets colder with altitude (roughly -62 f at the top) Acts as a cap that limits mixing between the troposphere and stratosphere. Similar in composition to the troposphere, but 1000 times drier and less dense.
