Sources of Carbon Cycle

Sources of Carbon
Carbon dioxide which is predominantly present in air is also found in the
soil and oceans (dissolved CO₂)

Most of the earth's carbon is locked up in fossil fuels as carbonates. 10% of CO₂ is released through industrial and human activities like burning of fossil fuels, agricultural activities and forest clearing and burning. CO₂ is also released by soil microbial respiration. gives the sources of carbon.

Table 42.1 Various sources of carbon

Sink	Amount in billions of metric tons
Atmosphere	578 (as of 1700) to 766 (as of 1999)
Soil organic matter	1500 to 1600
Ocean	38,000 to 40,000
Marine sediments and sedimentary rocks	66,000,000 to 100,000,000
Terrestrial plants	540 to 610
Fossil fuel deposits	4000

The carbon cycle has two parts:

Slaw cycle Here the carbon turnover is measured in 100s and 1000s of years involving weathering of rocks and dissolution of carbonates on land and oceans.

Fast cycle Carbon turnover measured in years or in decades. This is biological in nature. This cycle directly affects and is affected by soil microbes. A schematic representation of the carbon cycle
