10:23 AM Sanders 7.9 Greenhouse Effect Unit 7: Water Cycle and Climate

10:23 AM Unit 7: Water Cycle and Climate Vocabulary  Global Warming: an increase in average Earth temperatures  Greenhouse Gases: infrared radiation is absorbed by carbon dioxide, water vapor, methane, and other gases in the atmosphere  Global Warming: an increase in average Earth temperatures  Greenhouse Gases: infrared radiation is absorbed by carbon dioxide, water vapor, methane, and other gases in the atmosphere

10:23 AM Energy  Everything you do or that is done in the universe, involves the use of energy. Unit 7: Water Cycle and Climate

10:23 AM Energy from the Sun Unit 7: Water Cycle and Climate

10:23 AM Energy Transaction  In any energy transfer, there is a reduction in energy with heat as a by product.  What wavelength is reflected from visible light?  In any energy transfer, there is a reduction in energy with heat as a by product.  What wavelength is reflected from visible light? Unit 7: Water Cycle and Climate

10:23 AM Greenhouse Effect  Earth’s surface radiation consists mostly of long infrared radiation, which can be absorbed by greenhouse gases.  Carbon dioxide  Water vapor  Methane  Other gases in the atmosphere  Earth’s surface radiation consists mostly of long infrared radiation, which can be absorbed by greenhouse gases.  Carbon dioxide  Water vapor  Methane  Other gases in the atmosphere Unit 7: Water Cycle and Climate

10:23 AM How does the Greenhouse Work?  Absorption of infrared warms the atmosphere and causes it to act as a blanket Unit 7: Water Cycle and Climate

10:23 AM What Happens  The overall effect is a global temperature between 55 o F and 60 o F.  It would otherwise average 0 o F.  The overall effect is a global temperature between 55 o F and 60 o F.  It would otherwise average 0 o F. Unit 7: Water Cycle and Climate

10:23 AM Global Warming  In recent years, there has been a concern that the greenhouse effect may be causing global warming.  This is an increase in temperature. Unit 7: Water Cycle and Climate

10:23 AM Fossil Fuels  The burning of fossil fuels releases additional carbon dioxide and other greenhouse gasses into the atmosphere. Unit 7: Water Cycle and Climate Above is a traffic jam in China that lasted over 9 days.

10:23 AM Sources of Greenhouse Gasses  Water vapor is the most effective greenhouse gas.  Methane, the gas with the greatest affinity for warming the atmosphere comes form cows. August 14, 2015Unit 7: Water Cycle and Climate
