1. Carbon Slowly Returns to Atmosphere from Rocks and Soil
Volcanic Eruptions ADD CO2
Carbon Is STORED in rocks and underground deposits is released very slowly into the atmosphere as CO2.

2. Oceans are the largest SINKS/STORAGE for Carbon
Diffusion =
Moves CO2
From atmosphere to Oceans. High concentration to low
Concentration.
(LOTS  LITTLE)

3. **MORE CO2 ABSORBED = MORE ACID CREATED = MORE ACIDIC OCEAN WATER

4. Plants/phytoplankton REMOVE CO2 for photosynthesis.
Many animals REMOVE bicarbonate from water to use in building shells
Animals die and carbon substances are deposited at the bottom of the ocean.

5. Burning wood & Fossil Fuels (Combustion)
ADD CO2 back into the atmosphere
* one gallon of gas burned in a car =19lbs of CO2

6. Rocks & Sediments (fossil fuels ). Living Organisms
WHERE CARBON IS STORED…
Atmosphere
Oceans
Rocks & Sediments (fossil fuels ).
Living Organisms

7. Major Sources of Carbon
Respiration
Burning Fossil Fuels (Combustion)
Cow Farts (Methane)
Volcanic Eruptions
Decomposition
