- Water and Carbon Cycles - 2
- The Carbon Cycle - Systems
- Where is it Found?
- all systems
- organic stores
- living things
- inorganic stores
- rocks
- fossil fuels
- Lithosphere
- sedimentary rocks
- 99.9%
- fossil fuels
- 0.004%
- sedimentary rocks
- Hydrosphere
- CO2 dissolved in rivers/lakes
- oceans
- 0.04%
- Atmosphere
- CO2 & CH4
- carbon dioxide
- methane
- 0.001%
- CO2 & CH4
- Biosphere
- living orgaisms
- die and decay
- carbon -> soil
- die and decay
- 0.004%
- living orgaisms
- Cyrosphere
- - 0.01%
- permafrost
- decomposing plants & animals
- Where is it Found?
- Transferring Carbon
- Closed System
- inputs & outputs
- energy
- carbon
- stays same
- inputs & outputs
- Long-Term Stores
- rock
- fossil fuels
- Stores
- vegetation
- atmosphere
- soil
- fossil fuels
- earth crust
- sediment
- ocean
- Transfers
- combustion
- respiration
- sequestration
- ocean uptake
- decomposition
- Closed System
- Size of Carbon Stores
- Carbon Flows
- Overtime
- Photosynthesis
- atmosphere -> biosphere
- CO2+water = glucose+O2
- passed through food chain
- respiration
- decomposition
- Combustion
- decomposed biomass -> atmosphere
- ocean -> atmosphere
- wildfires
- Sequestration
- captured
- sedimentary rocks
- fosil fuels
- sequestered till burned
- captured
- Time and Scale
- Carbon Flows
- Fast Carbon Flows
- photosynthesis
- respiration
- combustion
- decomposition
- Slow Carbon Flows
- sequestration
- Spatial Scale
- e.g. plant scale
- photosynthesis
- respiration
- e.g. ecosystem scale
- combustion
- decomposition
- e.g. plant scale
- Changing the Carbon Cycle
- Natural
- wildfires
- biomass -> atmosphere
- large quantities
- growth of plants
- volcanic activity
- carbon in magma
- -> atmosphere - CO2
- decreasing emissions
- wildfires
- Human
- deforestation
- agriculture
- development
- reduces store
- biosphere -> atmosphere
- farming
- animals release CO2 & CH4
- ploughing releases CO2
- + population = + CO2
- hydrocarbon extration - fossil fuel
- extracting
- burning
- release CO2 -> atmosphere
- deforestation
- Natural
- Atmosphere, Land & Oceans
- Atmosphere & Climate
- greenhouse gases
- trap suns energy
- concentration+ temps rise
- global warming
- temp change - affect climate
- e.g. storms
- greenhouse gases
- Land
- plants grow
- no carbon = no photosynthesis
- + temps = + wildfires
- can reduce CO2 in land
- released permafrost
- Oceans
- CO2 dissolved in ocean from atmosphere
- C02 used by...
- plankton
- seaweed
- + acidity
- global warming effect
- warm water - less absorbing
- Atmosphere & Climate
- Carbon Budget
- Definition
- balance between inputs and outputs
- Carbon Source
- inputs < outputs
- Carbon Sink
- inputs > outputs
