outermost layer; transition zone between the earth's atmosphere and outer space; has satellites
exosphere
bad mix of sulfur dioxide, sulfuric acid, and particulates
industrial smog
atmospheric layer closest to the earth's surface; supports life
troposhpere
major outdoor pollutants
--carbon oxides --nitrogen oxides and nitric acid --sulfur dioxide and sulfuric acid --particulates (suspended particulate matter) --ozone --volatile organic compounds (VOC)= hydrocarbons, methane, benzene, and liquid solvents
atmosphere is split into 4 layers-- name them lowest to highest
--troposphere --stratosphere --mesosphere --thermosphere --exosphere
6 factors that increase air pollution
--urban buildings= slow wind speed and reduce removal/dilution of pollutants --hills and mountains= reduce air flow and build-up occurs --high temps --emissions of volatile organic compounds --vertical movement of air --air pollution can move from 1 country to another

c. Climate tipping points
How could a hole in the ozone layer accelerate global warming? a. The oceans would become overheated from excess solar energy. b. Long wave radiation from the sun will reach the earth. c. Ultraviolet radiation could destroy CO2 consuming photosynthetic organism in the oceans. d. Increased sunlight could create dangerous levels of smog. e. An ozone hole represents one of the climate tipping points.

coldest layer; burns up most meteors and asteroids before they are able to reach the earth's surface
mesosphere
found in stratosphere; layer of gaseous ozone (O3) in the stratosphere that protects life on earth by filtering out most harmful UV radiation from sun
ozone layer
contains earth's protective ozone layer
stratosphere
protects the earth, enabling space exploration and communication. It recycles water, absorbs the sun's energy and creates a moderate temperature
thermosphere
consists of short-term changes in atmospheric variables (temp, rain within day)
