Weather and Climate Final Study Guide 20:50 ABOUT A 60 QUESTION EXAM HALF NEW STUFF, OTHER HALF OLD MIDTERM INFORMATION Weather Discussions-  Visible- sky is black Infrared- sky is white High clouds whiter Station model- know the symbols (not hard) Atmospheric Structure and Composition Earth’s Current Atmosphere  Ozone “colonizes” dry land and oxygen makes it so BIG  animals can live here and breathe 1. Nitrogen----78% 2. Oxygen------21% 3. Argon--------1% 4. TraceGases: 5. Carbon Dioxide--------0.038% 6. Methane-----------------0.00017% 7. Ozone--------------------0.000004% 8. Chlorofluorocarbons--0.00000002% 9. Water Vapor-----------highly variable (0-4%) 10. Two Billion Years Ago     11. Earth’s Atmosphere then:   He and H are so light that they escaped the pull  of Earth’s gravity over time

Methane CH 4 Ammonia NH 3 Nitrogen N 2 12. Carbon Dioxide CO 2   (very carbon dioxide rich, volcanoes) 13. Argon Ar 14. Water Vapor H 2 O 15. Neon Ne 16. Krypton Kr 17. Four Billon Years ago        Big Bang formed stars and the universe was  composed of H and He  18. Earth’s Atmosphere then:  19. Helium He 20. Hydrogen H 21. Methane CH 4 22.Ammonia NH 3 23.Vertical Structure of Atmosphere     : Troposphere- 0 to 10 km, where we live, lots of weather, temperature decreases with  height, air convects Tropopause-where temperature levels off, after there temperature starts to rise again,  around 10 km up Stratosphere- temperature increases with height, stable, no weather, planes fly here  (less turbulence), warms with height because of  presence of ozone, ozone maximum  here, protects us from UV rays, around 10-50 km Stratopause- marks the top of the stratosphere around 50 km up Mesosphere-heating because of absorption of UV by ozone, temperature decreases  with altitude, 50 to 85 km Mesopause- marks the end of the mesosphere around 85 km up

Thermosphere- warms with height, high energy UV rays, photodissociation warms  air, density of atmosphere is so low that by 120 km it begins to mix with  interplanetary space TODAY SUCKS MA TITTIES Energy, Temperature, and Heat Kinetic Energy- the work that a body can do by virtue of its motion; example- a sports  car has more kinetic energy than a regular car moving at the same speed Potential Energy- the work an object can do as a result of its relative position; example-  you do work as you lift a book off a desk, once off the desk, the book has potential to do  work because of gravity.  The higher you lift the book the more potential energy you  have, when you let go of the book and it falls, the potential energy turns into kinetic
