| A | B |
|---|
| Composition of Earth's Atmosphere | Oxygen-21%, Nitrogen-78%, Others-1% |
| Temperature of atmosphere | increase/decrease as it goes thru the layers |
| Heterosphere | air changes, not the same % of composition as homosphere |
| Homosphere | same composition of air and % throughout, molecules more dense as they are drawn to the earth by gravity |
| Temperature designations in Homosphere | Troposphere, Stratosphere, Mesophere |
| Temperature designations in Heterosphere | Thermosphere |
| Ionosphere | electronically charged ions - particles from the sun, heats up |
| Ozonosphere | 20 mi. thick, protects us from sun's ultraviolet radiation |
| Thermopause increase/decrease | Troposphere-decrease, Stratosphere-increase, Mesophere-decrease, Thermosphere-increase, Exosphere-thermopause increase |
| density | volume measurement for air pressure |
| natural atmospheric pollutions | volcanic eruptions, forest first, salt spray |
| 3 natural factors effecting pollution | valleys-cause pollution to accumulate & traps them, Wind-carries pollution, temperature |
| Earth's ozone | created by photochemicals |
| Normal lapse rate | average - take data over time and average |
| Environmental lapse rate | what is the actual data - today at a particular location |
| Effects of Clean Air act | less lead in air, less pollution related deaths, restrictions on autos, building, chemical emissions |
| anthropogenic | human caused |
| temperature inversion | normal temps reverse trends and begin to increase at some point |
