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)

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

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

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

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

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

Q

Why might increased CO2 not always increase plant growth?

A
  • plants need other factors to grow, such as rainfall, temperatures and other nutrients
