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.

6. Divided into two components:
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

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

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

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

13. 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

14. 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

15. 6CO2 + 6H2O + light energy → C6H12O6 + 6 O2
PHOTOSYNTHESIS
Producers take in carbon dioxide, water, and sunlight to produce sugars and oxygen
Chemical Formula:
6CO2 + 6H2O + light energy → C6H12O6 + 6 O2

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

17. 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.

18. 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)
