Although the amount of carbon is finite and fixed, it is dynamic, moving between living and nonliving things. This statement adequately describes the carbon cycle in a single sentence. Relatively balanced in fluctuations in the past, the carbon cycle has been affected by the actions and influence of humans. One major example of this would be the contribution of carbon into the atmosphere, resulting in changes of weather patterns, oceanic chemistry and movements, etc. Connected by carbon exchange routes, the common divisions of the carbon cycle have been generally recognised to be as follows:The BiosphereThis division consists of all carbon in land-living organisms, along with the carbon in soils. Majority of the carbon in this system is organic carbon, with both above-ground living organisms and soils combined, there are roughly 2,000 gigatons of carbon stored altogether.The carbon in this system can leave through rivers, streams, erosion, combustion/respiration of carbon released into the atmosphere, etc.Earth’s Interior Operating relatively slow when considering the speed of other systems, the carbon in the earth’s interior is one of the most important factors in determining the amount of carbon in the atmosphere, and ultimately global temperatures. Most of the carbon on the planet is stored in the interior, stagnant and inert. The carbon in this system has the ability to ‘leave’ in several ways, such as being removed by human action, in drilling for fossil fuels. However, perhaps the most fascinating of all the removals of carbon is through volcanic activity, being released into the atmosphere and oceans through hotspots in the earth’s interior.The AtmosphereExisting in two main forms, methane and carbon dioxide, carbon in the atmosphere plays an influential role in the cycle. With the ability to absorb, retain and reflect heat, the carbon in the atmosphere can create devastating greenhouse effects of which can have a large effect on our entire planet. The carbon in this cycle is removed primarily through photosynthesis.The Oceanic Biosphere Possessing a similar influence to the atmosphere division, the oceanic biosphere contains the second largest amount of carbon of all divisions of the entire carbon cycle. Dissolved, inorganic carbon in the oceans can be stored in deeper layers of the oceans for long periods of time. Majority of the carbon in this system enters through the dissolution of carbon dioxide from the atmosphere. It is worth noting that carbon dioxide increases the acidity of the ocean, understandably affecting oceanic biosystems, mostly for the worse.
