- The ways in which the two cycles link and are interdependent via oceans, atmosphere, cryosphere and vegetation.
- Atmosphere
- Atmospheric CO2 has a greenhouse effect
- CO2 plays a role in the photosynthesis by terrestrial plants and phytoplankton
- Plants, which are important carbon stores, extract water from the soil and transpire it as part of the water cycle.
- Water is evaporated from the oceans to the atmosphere, and CO2 us exchanged between the stores
- Plants, which are important carbon stores, extract water from the soil and transpire it as part of the water cycle.
- CO2 plays a role in the photosynthesis by terrestrial plants and phytoplankton
- Atmospheric CO2 has a greenhouse effect
- Oceans
- Ocean acidity increases when exchanges of CO2 are not in balance
- The solubility of CO2 in the oceans increases with lower SST
- Atmospheric CO2 levels influence: SSTs and the thermal expansion of the oceans; air temperatures; the melting of ice sheets glaciers; and sea level
- The solubility of CO2 in the oceans increases with lower SST
- Ocean acidity increases when exchanges of CO2 are not in balance
- Cryosphere
- CO2 levels in the atmosphere determine the intensity of the greenhouse effect and the melting of ice sheets, glaciers, sea ice and permafrost
- Melting exposes land and sea surfaces which absorb more solar radiation and raise temperatures further
- Permafrost melting exposes organic material to oxidation and decomposition which releases CO2 and CH4
- Run-off, river flow and evaporation respond to temperature change
- Permafrost melting exposes organic material to oxidation and decomposition which releases CO2 and CH4
- Melting exposes land and sea surfaces which absorb more solar radiation and raise temperatures further
- CO2 levels in the atmosphere determine the intensity of the greenhouse effect and the melting of ice sheets, glaciers, sea ice and permafrost
- Vegetation and Soils
- Water availability influences the rates of photosynthesis, NPP, inputs of organic litter to soils and transpiration
- The water-storage capacity of soils increases with organic content
- Temperatures and rainfall affect decomposition rates and the release of CO2 into the atmosphere
- The water-storage capacity of soils increases with organic content
- Water availability influences the rates of photosynthesis, NPP, inputs of organic litter to soils and transpiration
- Atmosphere
