Greenhouse Effect Power Point

  1. 1. Greenhouse Effect and Global Warming
  2. 2. <ul><ul><li>Rise in Earth’s temperature </li></ul></ul><ul><ul><li>By certain atmospheric gases </li></ul></ul><ul><ul><li>That trap the Sun’s energy </li></ul></ul>What is the Greenhouse Effect?
  3. 3. Examples of Heat Trapping Gases <ul><li>Water vapor (H 2 O) </li></ul><ul><li>Carbon dioxide (CO 2 ) </li></ul><ul><li>Nitrous oxide (N 2 O) </li></ul><ul><li>Methane (CH 4 ) </li></ul>
  4. 4. Why are the Gases Important? <ul><li>Heat would escape back into space </li></ul><ul><li>Earth’s temperature would be 60 ºF colder </li></ul><ul><li>Makes Earth suitable for life </li></ul>
  5. 5. Greenhouse Effect Examples: <ul><li>Trap heat from sun </li></ul><ul><li>Glass lets in light </li></ul><ul><li>Glass keeps heat from escaping </li></ul><ul><li>Causes greenhouse to heat up </li></ul>Greenhouse
  6. 6. Greenhouse Effect Examples: <ul><li>Glass lets in light </li></ul><ul><li>Glass keeps heat from escaping </li></ul><ul><li>Causes the car to heat up </li></ul>Car Parked in Sunlight
  7. 7. Process of the Greenhouse Effect
  8. 8. Process of the Greenhouse Effect <ul><li>Sun’s energy passes through atmosphere </li></ul><ul><li>26% is reflected or scattered </li></ul><ul><li>19% absorbed by clouds, gases, and particles </li></ul><ul><li>4% reflected to space by surface </li></ul><ul><li>51% reaches the surface </li></ul>
  9. 9. What is the Energy Used for? <ul><li>Heating of the ground </li></ul><ul><li>Melting of ice and snow </li></ul><ul><li>Evaporation of water </li></ul><ul><li>Plant photosynthesis </li></ul>
  10. 10. Possible Causes of the Greenhouse Effect <ul><li>Deforestation and agriculture </li></ul><ul><li>Burning of fossil fuels, gasoline, oil </li></ul><ul><li>Burning of wood and coal </li></ul><ul><li>CFC’s </li></ul><ul><li>Population Growth </li></ul>
  11. 11. A Better Look... http://earthguide.ucsd.edu/earthguide/diagrams/greenhouse/
  12. 12. Why is it Dangerous? <ul><li>Global Warming </li></ul><ul><li>Endangered Species </li></ul><ul><li>Climate Change </li></ul>
  13. 13. What is Global Warming? <ul><li>Heat trapped inside Earth </li></ul><ul><li>General warming effect created </li></ul><ul><li>Increase in air and ocean temperatures </li></ul><ul><li>Vital issue in society </li></ul>
  14. 14. Causes of Global Warming <ul><li>Greenhouse gases increase through human activity </li></ul><ul><li>Deforestation </li></ul><ul><li>Use of fertilizers </li></ul><ul><li>Burning of organic matter </li></ul><ul><li>Burning of fossil fuels </li></ul>
  15. 15. Consequences of Global Warming <ul><li>Climate changes </li></ul><ul><li>Changes in wildlife adaptations and cycles </li></ul><ul><li>Melting of polar ice caps </li></ul><ul><li>Increase in sea level </li></ul><ul><li>Flooding in coastal areas </li></ul><ul><li>Ocean Acidification </li></ul>
  16. 16. More Consequences <ul><li>Species becoming endangered/extinct </li></ul><ul><li>Heavy drought </li></ul><ul><li>Spread of disease </li></ul><ul><li>Rise in tides </li></ul><ul><li>Change in weather patterns </li></ul>
  17. 17. Future Outlook of Glabal Warming <ul><li>Natural resources depleted </li></ul><ul><li>Need balance between environment and industry </li></ul><ul><li>Greenhouse gas emissions reduced by 80% </li></ul>
  18. 18. What Can We Do to Help? <ul><li>Reforestation </li></ul><ul><li>Personal Actions </li></ul><ul><li>Climate Policy </li></ul>
  19. 20. <ul><li>Put notes away </li></ul><ul><li>Pull out a sheet of paper </li></ul><ul><li>Answer the following questions </li></ul><ul><ul><li>Describe the greenhouse effect </li></ul></ul><ul><ul><li>List the possible causes of greenhouse effect </li></ul></ul><ul><ul><li>List the possible causes of global warming </li></ul></ul><ul><ul><li>List the consequences of global warming </li></ul></ul>
