Carbon - Factors Driving Change In Magnitude Of Stores Over Time Flashcards
Atmosphere to biosphere
CO2 - taken by plants - photosynthesis- grow - goes up foodweb (herbivore, carnivore, omnivore)= sequestration
Biosphere to atmosphere
Respiration and decomposition
Biosphere to lithosphere
Carbon in form of DOM enter soil
Decomposition
Can remain for 100s of years
Atmosphere to ocean
CO2 diffuses in ocean - remains
Marine organisms - make calcium carbonate - create shells
Ocean to atmosphere
CO2 diffused from ocean to atmosphere - reverse of atmosphere to ocean
Ocean to lithosphere
Sedimentation
Long term carbon store
Lithosphere to atmosphere
Volcanic eruptions
Combustion through burning fossil fuels
Lithosphere to ocean
Acid rain
CO2 absorbed by rain water - chemical weathering
Carbon stored in rocks is released and is now dissolved and then carried by the water cycle to oceans
