Presentation Transcript

  1. Please get out your Obj #1&2 for a stamp Please pass back the updated unit calendar and read the board. 3,2,1 . . .Blast off!

  2. The Greenhouse effect • Solar radiation in with shorter wavelengths • Converted to infrared energy at surface with longer wavelength • Infrared energy trapped by greenhouse gases

  3. Greenhouse gases • CO2

  4. Methane CH4 (25x more heat trapping ability than CO2!)

  5. N2O Nitrous Oxide

  6. Water!

  7. CFC’s (chlorofluorocarbons)

  8. And O3

  9. Greenhouse Warming potential

  10. Atmosphere diagram – the last story! • Sources on this sheet just like the others • Show primary pollutants coming from each source correctly (greenhouse gases) • Draw in greenhouse effect in green (get it?)

  11. Why are these biomes in these places? What shapes climate?

  12. Earth’s axis – 23o tilt = seasonality

  13. Ocean currents also affect biome distribution.

  14. Rome is same latitude as New York!

  15. Normal conditions: winds blow west, cold waters rise El Nino: winds stop blowing, warm waters in Eastern Pacific block cold waters Effects: disrupt marine ecosystems, major weather changes over 2/3 Earth El Nino

  16. La Nina

  17. El Nino Southern Oscillation vs. La Nina

  18. Check for understanding • Name the 6 green house gases. • What human activities create CH4? • Is the greenhouse effect beneficial or negative? • What energy type reaches the earth from the sun?
