  1. CARBON CYCLE

  2. ELEMENT: CARBON 6 Protons 6 Neutrons 6 Electrons 4th Most Abundant Element on Earth

  3. Carbon’s Past • 3,000 B.C. -Used by Egyptians and Sumerians in the manufacturing of BRONZE • The first true chemical analyses were made in the 18th century • 1789 carbon was listed by Antoine Lavoisier as an element. 

  4. What is the Carbon Cycle? • the movement of carbon as it is recycled and reused throughout the biosphere. • Carbon is exchanged among the • Biosphere • Pedosphere • Geosphere • Hydrosphere • Atmosphere. Bio – Pedo- Geo- Hydro-

  5. Organic vs. Inorganic • ORGANIC: • INORGANIC: related to living matter. Not from plants or animals

  6. Carbon Cycle • Divided into two components: • -Biological Carbon Cycle • -Geological Carbon Cycle

  7. Geological Process • Most of the earth's carbon is stored in the Earth’s Lithosphere •  80% is LIMESTONE •  20% is stored as KEROGENS

  8. Geological Process • Limestone -  sedimentary rock composed of largely the minerals calcite and aragonite, which are different forms of calcium carbonate (CaCO3).  Kerogens - is a mixture of  organic chemical compounds. Most CARBON got there during the formation of the Earth

  9. Carbonic acid combines with minerals on the earth’s surface forming carbonates (weathering)

  10. Carbonates erode from the surface into the ocean and settle on the ocean floor

  11. Sinks into the earth, heats up, and eventually rises up as carbon dioxide into the atmosphere

  12. GEOLOGICAL CARBON CYCLE • Carbon dioxide diffuses into the ocean forming bicarbonates or calcium carbonate (used to make shells and other body parts by organisms such as coral and brachiopod shells) • These organisms die and their shells and body parts become carbonate-rich deposits • After a long period of time, these deposits become sedimentary rocks, coal, or oil • Ocean Carbon Cycle

  13. BIOLOGICAL CARBON CYCLE • The movement of carbon through the processes of photosynthesis and cellular respiration • Also, the consumption of living matter by other organisms • The amount of carbon cycled through annually is a 1,000 times greater than the geological carbon cycle component

  14. PHOTOSYNTHESIS • Producers take in carbon dioxide, water, and sunlight to produce sugars and oxygen • Chemical Formula: 6CO2 + 6H2O + light energy → C6H12O6 + 6 O2

  15. RESPIRATION • Carbon dioxide is released back into the atmosphere by breaking down sugar during cellular respiration • Chemical Formula: C6H12O6 + 6O2 → 6CO2 + 6H2O + energy

  16. The Bio-Carbon Cycle • 1. Producers take in Carbon through PHOTOSYNTHESIS • 2. Consumers take in carbon by eating consumers and producers. • 3. Consumers release Carbon in the form of CO2 • 4. Consumers die and their carbon goes into the soil.

  17. Carbon into the Air? • CO2 is also released into the atmosphere by: • Decaying dead matter • Forest fires • Volcanoes • Burning of fossil fuels (coal, oil, gas)

  18. The Carbon Cycle • Carbon Cycle • Carbon Cycle #2
