A
- photosynthesis+respiration+
decomposition
-human processes/combustion
-volcanic activity
-oceanic carbon pumps
-geology
1
Q
what is a carbon sink
A
a store that takes in more carbon than it releases
2
Q
what is a carbon store
A
a store that releases more carbon than it takes in
3
Q
geological component of the movement of carbon
A
of rock:
-weathering
-subduction
4
Q
what are the human activities which put carbon back into the atmosphere
A
-fossilfuel (+their extraction)
-agriculture
-deforestation
5
Q
what is the capure of carbon called
A
carbon sequestration
6
Q
what is carbon sequestration
A
when CO2 is captured and put into long term store
7
Q
effects of greenhouse gas on oceans
A
-sea levels rise(melting ice=no solar radiation reflection)-thermal expansion
-acidification
-reduced salinity
-warming(more phytoplankton=less photosynthesis)
