Mark the incorrect statement with reference to carbon cycle:
Correct answer: B. 75% of total carbon lies in geological component
- A. Lime rocks contribute to CO2 of water
- B. 75% of total carbon lies in geological component
- C. CO2 is returned by combustion of fuel
- D. Atmospheric CO2 gets dissolved in water
Explanation
Limestone weathering can add carbon dioxide to water, dissolved CO2 remains part of the cycle, and combustion returns CO2 to the atmosphere. The stated 75% figure is not correct for the geological carbon reservoir, which contains a much larger proportion of total carbon.
