Factors affecting the stores of carbon
Terms in this set (14)
the process by which green plants and some other organisms use sunlight to combine carbon dioxide from the atmosphere with water to form carbohydrates
this takes oxygen from the atmosphere and replaces it with carbon dioxide.
6CO2 + 6H2O + sunlight = C6H12O6 + 6O2
6O2 + C6H12O6 = energy + 6H2O + 6CO2
this includes physical, chemical and biological mechanisms that transform organic matter into increasingly stable forms.
this occurs when any organic material is reacted in the presence of oxygen to give off the products of carbon dioxide, water and energy.
the burning of living and dead vegetation, it includes human induces burning as well as naturally occurring fires.
this involves capturing carbon dioxide from the atmosphere and putting it into long-term storage.
carbon dioxide is captured at its source and then injected in liquid form into stores underground.
Terrestrial or biologic sequestration
this involves the use of plants to capture carbon dioxide from the atmosphere and then to store it as carbon in the stems and roots of plants as well as in the soil.
the breakdown of rocks in situ by a combination of weather, plants and animals
Ocean carbon pumps
the concept of vertical deep mixing where carbon dioxide is transported from the ocean surface to the ocean depths by sinking cold water in the high latitudes. if brought to the surface the cold water will warm up and release some of its carbon dioxide to the atmosphere
releases large amounts of Carbon into the atmosphere every year
The warming effect of volcanic activity
is counter balanced by outputs of Sulphur dioxide which form droplets of sulphuric acid which increase reflection of radiation in the atmosphere
