Physical factors,seasonal changes and stores and flows of Carbon Cycle #5 Flashcards
1
Q
What is the main carbon store?
A
Decomposed plant material in permafrost that has been there for 500,000 yrs.
2
Q
Why is there little photosynthesis and NPP?
A
There is little biomass from slow plant growth and little water in liquid form.
3
Q
What can low temps and waterrlogging cause?
A
slow decomposition and respiration.
4
Q
Why does rock have little influence on the carbon cycle?
A
Due to permafrost and geology’s impermeability, porosity and mineral composition of rock (not much carbon).
