Inter relationship of the cycles

Question 1

How the atmosphere links the cycles

Answer 1

Photosynthesis (process in carbon cycle) requires water and carbon
Water extracted form soil via plant (carbon store)
Increase carbon form ocean = increased evaporation of ocean

Question 1

How oceans link the cycles

Answer 1

Increased carbon = increased aciditiy (visa versa)
Increase SST = decrease CO2 soluability = increase CO2 in atmosphere (visa versa)
Increase CO2 in atmosphere = increased Sea ice melting

Question 2

How the cryosphere links the cycles

Answer 2

increased atmospheric CO2 = increased perm thawing
melting = increased albedo = melting
perm thaw = increased CO2 in atmosphere
run off, river flow and evap are dependent on temp

Question 3

how vegitation links the cycles

Answer 3

water level in soil and vegitation determines rate of photosynthesis (impacts NPP and level of organic matter in soil)
temp and precip effect rate of decomp and Photosynth.
increased CO2 in soil = increased water storage possible

Question 4

How long term climate change will effect the water cycle

Answer 4

increased evaporation
increaced precipitation (because of increased evaporation)
increased ectreme weather
decreased cryosphere storage
increased storage in ocean

Question 5

How long term climate change will effect the carbon cycle

Answer 5

increase biomass to atmosphere flow (eg decomp due to increase temp)
decreased rainforest (aridity in humid areas = more grassland)
increased boreal forest
less stored in cryosphere
acidification of ocean

Question 6

How human activity changes the availability of water stores

Answer 6

rivers (irrigation = decrease volume and land use change = change in peak discharge)
Aquifers (less volume lower water level)
Lakes (less stored)
Flows (increased surface run off due to urbanisation and deforestation)

Question 7

How human activity canges the availability of carbon stores

Answer 7

Geologicial stores (84% of world rely on fossil fuels for energy and thus carbon removed from geological store)
Atmosphere (8 billion tonnes of carbon burnt a year)
ocean (2.5 billion extra tonnes absorbed a year, leads to increase acidity which could kill phytoplankton which absorb half the excess CO2)
biosphere (2.5 billion extra stored due to emissions and deforestaiton leads to release of carbon from soil erosion)
