The biogeochemical cycle by which carbon is exchanged among the Earth systems.

One of the Earth's major carbon reservoirs

Atmospheric carbon plays an important role in the greenhouse effect.

(CH4) is mainly produced by the digestion or decay of biological organisms.

(CO2) has a large warming effect on global temperatures through the greenhouse effect.

Large amounts of carbon dioxide are dissolved in cold water in higher latitudes.

Silicate Stone absorbs carbon when it is exposed to the atmosphere during erosion.

Carbon is exchanged between the atmosphere and the geosphere

The balance of the exchanges of carbon between the carbon reservoirs of the carbon cycle.

Emissions by humans in the past 200 years has almost doubled the amount carbon dioxide in the air
