1. Chapter 6 Atmosphere APES

2. Atmosphere Invisble layer of gases that envelope Earth http://www.vtaide.c om/png/atmospher e.htm

3. Gases in Atmosphere

4. Function of Atmosphere Trap heat = warm planet Protect us from incoming UV, x-ray, cosmic radiation Without gases  no warming  no life

5. Layers of Atmosphere http://www.hippocampus.org/AP%20Environmental %20Science http://www.hippocampus.org/AP%20Environmental %20Science Troposphere – closest to surface contains weather and storm events Contains most clouds Stratosphere – steady wind present Commercial jets fly here Contains protective ozone layer ~ good ozone

7. Mesophere – lower temps Literally means middle sphere Thermosphere – rising temps Gases absorb UV radiation and become very active (KMT) thus increasing temps found here Aurora- lights in dark polar skies produced when charged particles from sun HIT oxygen or nitrogen molecule Satellites found here, important communication zone

9. Exosphere – this air converges with space

10. Weather vs. Climate What is wrong with the following statement? Global warming cannot be occurring, we had a very cool summer.

11. How does a tornado form?

12. Hurricanes, Cyclones, and Typhoons – OH MY! VIDEO link http://www.youtube.com/watch?v=GM-abtIT6Is

13. How does the sun warm planet Earth? GIANT CONVECTION CURRENT

14. What is wind? Horizontal movements of air resulting from changes in atm pressure + rotation of Earth Blow from HIGH atm pressure to LOW atm pressure http://www.hippocampus.org/AP%20Environme ntal%20Science http://www.hippocampus.org/AP%20Environme ntal%20Science

15. What is the Coriolis Effect? Air/water currents are deflected due to rotation http://www.youtube.com/watch?v=mcPs_Od QOYU http://www.youtube.com/watch?v=mcPs_Od QOYU http://www.youtube.com/watch?v=Wda7azM vabE&feature=related
