  1. Section 3 RadiativeBalance and the Natural Greenhouse Effect http://www.bing.com/images/search?q=greenhouse+effect&qpvt=greenhouse+effect&FORM=IGRE#view=detail&id=8E45E35656FC95CB71B1F6C4439D06AC9A3F534D&selectedIndex=49

  2. Learning Targets:  I can explain factors that cause the dynamic balance in the atmosphere to change.  I can model and explain the relationships and energy flow existing in various Earth systems (atmosphere) http://4nutshells.com/wp-content/uploads/2010/10/Earths-atmosphere.jpg

  3. 30. Earth exchanges energy with its environment primarily through transfers ofelectromagnetic radiation. http://uniteunderfreedom.com/wp-content/uploads/2013/01/electromagnetic.jpg

  4. 31. At anytime our planet is simultaneously absorbing energy from the sunand radiating energy back intospace. http://www.johnsonwindowfilms.com/dealer/images/art_148/SunWavesToEarthBlu.jpg

  5. Why does the temperature remains stable over long periods of time on Earth? The temperature remains stable because the planet radiates energy back to space at a rate that closely balances the energy input it receives from the sun. http://www.jamesrobertshaw.co.uk/wp-content/uploads/2011/06/The-sun-and-solar-radiation.jpg

  6. Radiation from the Sun with varying wavelengthsalong the electromagnetic spectrum is known as • solar radiation. List 3 types of radiation the Sun emits. visible light, ultraviolet and infrared radiation http://newheavenonearth.files.wordpress.com/2011/07/sun-rays-coming-out-of-the-clouds-in-a-blue-sky21.jpg?w=900

  7. 35. When visible solar radiation reaches Earth, it may be absorbed by clouds, the atmosphere, or the planet's surface. http://beyondweather.ehe.osu.edu/files/2011/02/web_heat-budget.jpg

  8. What raises Earth's surface temperature? Solar radiation is absorbed by the Earth’s surface and is transformed into heat energy. • Some outgoing infrared energy emitted from the Earth is trapped in the atmosphere and preventedfrom escaping to space, through a natural process called the greenhouse effect. http://www.enwin.com/kids/images/pic.greenhouse_effect.jpg

  9. Ar Ar Ar • The most abundant gases in the • atmosphere—nitrogen, oxygen, andargon—neitherabsorb nor emit terrestrial or solar radiation. Ar Ar http://www.windows2universe.org/earth/Atmosphere/images/chemistry_troposphere_sm.gif

  10. What in the atmosphere can absorb long-wave radiation? – clouds, water vapor, carbon dioxide, methane, and nitrous oxide http://icons.wxug.com/metgraphics/climate/sunearthdiagram.jpg

  11. Why is the amount of heat received by the surface actually much larger (3x) than the amount the surface receives in solar radiation? Due to the natural greenhouse effect, the result is a surface temperature on average around 15°C (60°F), as compared to temperatures colder than –18°C (0°F) if there were no greenhouse effect. http://images.cpcache.com/merchandise/514_400x400_NoPeel.jpg?region=name:FrontCenter,id:69231149,w:16
