1. Insolation and the Seasons Topic 6 Created by P. Bordas MS, CCC-SLP Remember to wait for the vocabulary word to pop up at the end! Can you guess it before it comes up?

2. Solar Radiation and Insolation

3. Insolation The portion of the sun’s output of electromagnetic radiation that is received by Earth at the outermost part of our atmosphere (INcoming SOLar radiATION) http://en.wikipedia.org/wiki/Insolation

4. Ozone A form of oxygen gas that absorbes nearly all ultraviolet radiation in Earth’s upper atmosphere http://ipy.nasa.gov/multimedia/m000000/m000000/m000001/160657main_OZONE_large_web.png

5. Angle of Incidence The angle at which the insolation strikes Earth’s surface http://content.answers.com/main/content/img/oxford/Oxford_Sports/0199210896.angle-of-incidence.1.jpg

6. Transpiration A process by which plants release water vapor into the atmosphere as part of their life functions http://www.fijiaquifer.com/images/Transpiration.jpg

7. Greenhouse Gases Carbon dioxide, water vapor, methane, and other gases in the atmosphere http://www.umich.edu/~gs265/society/greenhouseeffectexplained.gif

8. Global Warming An increase in average Earth temperatures http://ruby.fgcu.edu/courses/twimberley/EnviroPhilo/GlobalWarming.jpg

9. Heat Budget and Climate Change

10. Heat Budget The result of the balance between the total amount of energy an object receives and the total energy it emits or loses http://www.geography.hunter.cuny.edu/~tbw/wc.notes/2.heating.earth.surface/images/earth.atm.heat.budget.jpg

11. Ice ages Periods when glaciers advanced into the middle latitudes caused by shifts in heat balance http://www.cosmosmagazine.com/files/imagecache/news/files/news/20081113_ice_age.jpg

12. El Nino A warming event that occurs every 2 to 10 years in. The normally cold waters of the eastern Pacific Ocean, off western South America, are replaced with a vast area of warmer waters ://www.junglephotos.com/galapagos/satimages/othe rsatimages/elnino.jpg&imgrefurl=http://www.junglep hotos.com/galapagos/satimages/othersatimages/elni no.shtml&usg=__8K2ayh1m1DZm9GQzR6ViDb5Y D0w=&h=480&w=640&sz=30&hl=en&start=4&um=1 &itbs=1&tbnid=cv5vCcX6NoXviM:&tbnh=103&tbnw =137&prev=/images%3Fq%3Del%2Bnino%26hl%3 Den%26safe%3Dactive%26rlz%3D1T4GZAZ_enUS 316US317%26um%3D1
