Presentation Transcript

  1. Carbon Forms • Carbon Monoxide – CO: poisonous • Carbon Dioxide – CO₂: greenhouse gas, poisonous at high concentrations

  2. Carbon Sources 1. Fossil Fuels • Ex: Coal, oil, gasoline, natural gas, propane

  3. Carbon Sources 2. Graphite • Highest grade of coal • Conducts electricity • Used in pencils (lead) 3. Diamonds • Formed from coal that is under high pressure and heat 4. Wood

  4. Carbon Reservoirs • Atmosphere • Plants • Animals • Fossil Fuels • Rock • Soil • Wood • Ocean: called a carbon sink because it takes up excess CO₂ from the atmosphere

  5. Carbon Dioxide CO2 • 0.04% of the Atmosphere • Greenhouse gas • Byproduct of respiration • Needed for photosynthesis • Emitted as fossil fuels are burned • Harmful at high concentrations • Solid form is dry ice

  6. Why do we care? • CO₂ concentrations fluctuate over time • Levels are higher than they were 1000 years ago

  7. How does carbon get released into the atmosphere? • Animal Respiration • Burning fossil fuels • Turning on lights, driving cars, • Factories, burning coal • Volcanoes • Earthquakes • Forest fires • Oceans

  8. How does carbon get taken out of the atmosphere? • Photosynthesis • Oceans: carbon sink • Decaying organisms

  9. Carbon movies http://www.npr.org/news/specials/climate/video/

  10. Forms of Energy Used in the U.S.
