Absorption of Carbon Dioxide
- Carbon dioxide is a water soluble gas (it is the gas used in fizzy drinks) and dissolves readily.
- When the water vapour in Earth’s early atmosphere condensed large amounts of CO2 dissolved in the oceans.
- Carbonate substances were precipitated during this process which later formed sediments on the seabed.
- As marine life began to evolve sea creatures began to appear which used up the carbonates to form shells and skeletons.
- Green plants and algae began to evolve and absorbed considerable amounts of carbon dioxide during photosynthesis.
- When these creatures died, their remains locked the atmospheric carbon into the rocks and fossil fuels as they developed.
- This is how the large amounts of carbon dioxide in the early atmosphere were reduced.
