Found as carbon dioxide in the oceans.
Found as organic material - soild
= Carbon rich soil - waterlogged soil found in moorlands -> used as a fossil fuel.
living organic material.
Most active in terms of moving carbon.
Found as carbon dioxide and methane -
fossil fuels, carbonate based rocks
(limestone and chalk)
Part of the soil storage - permafrost, when the soil freezes
