Distribution Of Stores In The Carbon Cycle Flashcards
1
Q
Sedimentary rocks
Most stored in carbonated rocks eg, limestone
A
60,000 to 100 million GT
Residency time of 240- 300 million years ( really long time)
2
Q
Oceans
A
38,700 gt
Can be split into the deep ocean where more is stored than the surface
Deep ocean ( 38,100 gt) has a residency time of 1250 years whereas surface ( 1020 gt) is 25 years
3
Q
Atmosphere
A
600 Gt
Small storage but lots of processes flow into the atmosphere
Eg, terrestrial biomass, fossil fuel emissions, combustion and respiration
Residence time of 6 years
4
Q
Fossil fuels
A
4130 gt
5
Q
