  1. Carbon Cycle sccs.org.uk

  2. D19 • Explain how chemical and physical processes cause carbon to cycle through the major earth reservoirs.

  3. 4 Major Spheres • Biosphere • Atmosphere • Hydrosphere • Lithosphere/Geosphere whshonorses.wikispaces.com

  4. Biosphere • The part of the Earth where living things exist. • The part of the Earth that is capable of supporting life. http://www.biology-online.org/dictionary/Biosphere flmnh.ufl.edu wildarunachal.org

  5. Atmosphere • The whole mass of air surrounding the Earth kidsgeo.com vtaide.com http://www.merriam-webster.com/dictionary/atmosphere

  6. Hydrosphere • All the waters on the earth's surface, such as lakes and seas. Merriam-Webster kidsgeo.com natasha-hydrosphere.blogspot.com

  7. Lithosphere/Geosphere • The outer solid part of the earth, including the crust and uppermost mantle. oceansjsu.com exploratorium.edu http://earthquake.usgs.gov/learn/glossary/?term=lithosphere

  8. Short-term (Fast Track)Carbon Cycle • Photosynthesis • Respiration • Decomposition • Diffusion • Minutes to Years beta.lpb.org

  9. Long-term (Slow Track)Carbon Cycle • Weathering and erosion • Accumulation of carbon-rich plant and animal material in sediments • Fossil fuel formation • Millions of years beta.lpb.org climate.be

  10. Basic Pathways • Diffusion • Respiration • Photosynthesis • Eruption of Gases • Burial and Sedimentation • Weathering and Erosion

  11. Let’s put it together Respiration Human Alteration Photosynthesis Respiration Atmosphere Hydrosphere Biosphere Diffusion Eruption Diffusion Lithosphere Burial and Sedimentation Weathering and Erosion Photosynthesis

  12. Human Alterations

  13. Use of Fossil Fuels • Formed over millions of years • Originates from buried plant and animal material • How does it affect the C cycle? geothermal.marin.org kids.britannica.com thedailygreen.com

  14. Deforestation • Trees cut down and burned • Impacts temp. and stability of the soil • Soil erosion • Inc. in temp. because soil no longer covered by vegetation • How does it affect the C cycle? en.wikipedia.org time.com plu.edu

  15. Cement Manufacturing • Calcium carbonate heated to produce lime and CO2 • US: 7 – 10 billion metric tons of C per year • How does it affect the C cycle? stateoftheusa.org pmhl.co.uk

  16. Cattle Farming • Cattle burping and farting • Respiration • How does it affect the C cycle? environmentalparliament.org oklahomafarmreport.com

  17. Rice Farming • Flooding of rice paddies causes underwater organic matter to decompose • Methane (CH4) is released • How does it affect the C cycle? Rice Farming in Louisiana agrariancrisis.in Rice Farming in Spain geographyfieldwork.com geobloggingwithmark.blogspot.com

  18. Carbon Capture and Store • Carbon sequestration • Capturing C from power plants and pumping it underground • Expensive • How does it affect the C cycle? carboncapture.us
