The Carbon CycleCarbon Cycle- circulation of carbon atoms through various processesCarbon circulates betweenWater and airAir and groundAir and living thingsLiving things and groundImage obtained from: http://globecarboncycle.unh.edu/graphics/CCdiagramWEB.jpg

Carbon Cycle: Water and SkyCarbon in the air: CO2 gasDense; stays close to ground/sea levelHow it gets into water: UptakeCO2 absorbed by bodies of waterColder water- more CO2 can be absorbedQuestion: whats happening to ocean temperatures?

Carbon Cycle: Earths Breathing LifeCarbon in the air: CO2 gasHow it gets into organisms: PhotosynthesisPlants store carbon as sugarsFood web: consumers eat producers, those consumers get eaten, etc.Organisms use sugars to form carbon compoundsImage obtained from: http://images.nationalgeographic.com/wpf/media-live/photos/000/003/cache/mt-des-voeux_300_600x450.jpg

Carbon Cycle: Earths Breathing LifeCarbon in organisms: carbon compoundsHow it gets into the air: Respiration, DecompositionExhaling releases CO2 gas into atmosphereOrganisms die, decompose; bacteria & fungi release CO2 gasImage obtained from: http://images.nationalgeographic.com/wpf/media-live/photos/000/003/cache/mt-des-voeux_300_600x450.jpg

Carbon Cycle: Fossil FuelsCarbon in organisms: carbon compoundsHow it gets into the ground: FossilizationFormed from dead organismsVery particular conditions for dyingCannot be exposed to airSubmerged and/or buried shortly after deathBuried matter compacted by weight of soil above itHigh temperature, pressure forms fossil fuelsImage obtained from: http://www.wired.com/images_blogs/wiredscience/2010/01/coal_f.jpg

Carbon Cycle: Fossil FuelsFossil FuelsCoalOilNatural gasTake millions of years to formOlder fuel- more carbon stored per unit of volumeImage obtained from: http://www.wired.com/images_blogs/wiredscience/2010/01/coal_f.jpg

Problems With Carbon CycleOcean temperatures risingLess CO2 uptake, more CO2 releaseHuman influenceConsuming fossil fuelsChanges stored carbon compounds into CO2 gasDeforestationLess photosynthesis; less CO2 removed from atmosphereLess organisms to be fossilizedImage obtained from: http://1.bp.blogspot.com/_cwrSE63jF7Y/TGrnq9FhTnI/AAAAAAAAA5I/dOshgl6RNDY/s1600/coal_fired_power_plant.jpg
