The Earth's oceans contain a large amount of CO2 in the form of bicarbonate and carbonate ions â much more than the amount in the atmosphere. The bicarbonate is produced in reactions between rock, water, and carbon dioxide.
Carbon is found in the non-living part of the hydrosphere, atmosphere, and geosphere as: 1  carbonate (CaCO 3) rocks: limestone and coral. 2  dead organic matter, such as humus in soil. 3  fossil fuels from dead organic matter (coal, oil, natural gas). 4  carbon dioxide (CO 2) in the air.
