1. Atmosphere

2. divided into layers determined by variation of temperature with height. lowest level, Troposphere temperature decreases with height up to about 10 km. where weather occurs http://climate.nasa.gov/ClimateReel/27Storm s640360/ http://climate.nasa.gov/ClimateReel/27Storm s640360/

3. Stratosphere : temperature increases with height. The increase in temperature is caused by absorption of ultraviolet radiation by the ozone layer

4. STRATOSPHERE: O 3 molecule is made of 3 O atoms. UV light breaks up O 2. Then one O can combine with O 2 to form O 3. O 2 formed by photosynthesis (plants) in the troposphere. If if were not for plants, we would not have an O 3 layer.

5. STRATOSPHERE: Less mass found here Ozone is the most important molecule (in lower layers of stratosphere; first 10 miles). 3 pennies stacked up is the size of the O 3 layer if condensed down. O 3 absorbs UV light O 3 destruction is = to reformation in a healthy functioning system (O 3 --- O 2 + O) Now O 3 destruction is happening more than O 3 reformation CFC’s; Chlorine portion is the culprit

6. Mesosphere: temperature decreases with height. ionosphere, the highest layer in the atmosphere temperatures increase with height due to ultraviolet radiation.

7. Acceleration of Greenhouse Effect…Global Warming: Too much heat is trapped. Have measured increase in greenhouse gases such as CO 2 and the rise in temperature for 150 years. Two major causes for increase in CO 2 : industry/power plants and automobiles. http://climate.nasa.gov/ClimateReel/C arbonCrisis/ http://climate.nasa.gov/ClimateReel/C arbonCrisis/ CO 2 CO 2 CO 2 CO 2 CO 2 CO 2 CO 2 CO 2 CO 2
