|---|---|---|---|---|---|
| the three forms of carbon | inorganic, organic, gaseous
🗑
|
||||
| what is an equilibrium | a balance between the production and absorption
🗑
|
||||
| three types of stores | oceanic, atmospheric and terrestrial
🗑
|
||||
| what is a carbon sink and carbon source | a carbon sink is store that takes more carbon in then in emits eg a tropical rainforests, wetlands and the tundra . a carbon source is something that give out more carbon the it absorbs
🗑
|
||||
| what is carbon sequestration | storing or capturing atmospheric carbon eg trees/ micro organisms
🗑
|
||||
| the main store of carbon | the lithosphere
🗑
|
||||
| fluxes in the carbon cycle | photosynthesis, respiration, combustion, decomposition, diffusion, sedimentation, weathering erosion, volcanic out gassing
🗑
|
||||
| variations in the fluxes | ecosystems effect deposition eg wetlands or the tundra, seasonality in the north plants die during winter which increases co2 levels, deforestation, afforestation, soil type clay soil stores more carbon
🗑
|
||||
| what are the three ocean pumps | physical, biological, carbonate pump
🗑
|
||||
| explain the green house effect | the sun give out shortwave inferred radiation some of this is trapped in the earths atmosphere which reflected of the land which warms up the world
🗑
|
||||
| what is the albedo effect | when solar radiation is reflected off ice and snow as it white (90%) while the sun is absorbed by the ocean as its darker. this is a preamble as the ice is melting
🗑
|
||||
| atherogenic effects | after the industrial revolution 75% of carbon emissions have been for fossil fuels
🗑
|
||||
| what human effects have been an issues | agriculture, deforestation (20%), urbanisation, combustion of fossil flues
🗑
|
||||
| effects of the enhanced green house effect | temperatures have increased which effects the albedo effect this have lead to rising sea levels. extreme weather events have become more common, reduced biodiversity and put us near a tipping point due to the positive feedback loop
🗑
