Greenhouse Effect PowerPoint

  1. 1. •Rise in Earth’s temperature•By certain atmospheric gases•That trap the Sun’s energy
  2. 2. •Water vapor (H2O)•Carbon dioxide (CO2)•Nitrous oxide (N2O)•Methane (CH4)
  3. 3. •Heat would escape back into space•Earth’s temperature would be 60ºF colder•Makes Earth suitable for life
  4. 4. •Trap heat from sun•Glass lets in light•Glass keeps heat fromescaping•Causes greenhouse to heatup
  5. 5. •Glass lets in light•Glass keeps heat from escaping•Causes the car to heat up
  6. 6. •Sun’s energy passes through atmosphere•26% is reflected or scattered•19% absorbed by clouds, gases, and particles•4% reflected to space by surface•51% reaches the surface
  7. 7. •Heating of the ground•Melting of ice and snow•Evaporation of water•Plant photosynthesis
  8. 8. •Deforestation and agriculture•Burning of fossil fuels, gasoline, oil•Burning of wood and coal•CFC’s•Population Growth
  9. 9. http://earthguide.ucsd.edu/earthguide/diagrams/greenhouse/
  10. 10. •Greenhouse gases increase through human activity•Deforestation•Use of fertilizers•Burning of organic matter•Burning of fossil fuels
  11. 11. •Climate changes•Changes in wildlife adaptationsand cycles•Melting of polar ice caps•Increase in sea level•Flooding in coastal areas•Ocean Acidification
  12. 12. •Species becoming endangered/extinct•Heavy drought•Spread of disease•Rise in tides•Change in weather patterns
