Interrelationships Flashcards
1
Q
How does atmospheric carbon impact the water cycle?
A
- increase in temperatures
- decrease in cryosphere stores of water
- increase H2O vapour stored in the atmosphere (climate feedbacks)
2
Q
How is water important to the slow carbon cycle?
A
- a medium through which carbon released through weathering is transported
- oceans
3
Q
How does hydrosphere water link to the carbon cycle?
A
- large oceans allow the physical pump
-tis can store carbon at great depths for a long period of time
4
Q
What is an example of positive feedback linking water and carbon cycles?
A
- carbon fertilisation
- increases tree growth, removes CO2
- this increases transpiration and interception
5
Q
How does the water cycle link to the biological carbon cycle?
A
- water needed for plant growth
- plants store carbon and sequester it in photosynthesis
6
Q
What is a human link between water and carbon cycles?
A
- urbanization; manufacturing of cement used in cities (8% emissions)
- also impacts water cycle as impermeable surfaces lead to SRO
7
Q
How does the water cycle impact the pedosphere?
A
- increased precipitation
- increases likelihood of sheet erosion
- pedosphere stores 3 x more carbon than the atmosphere
8
Q
Why might increased CO2 not always increase plant growth?
A
- plants need other factors to grow, such as rainfall, temperatures and other nutrients
