Slide 3
About Carbon Carbon is essential ingredient to life All known
life on Earth is carbon-based Organic- made of carbon compounds
Carbon moves among Earths 4 spheres Atmosphere (sphere of air)-
near the ground Hydrosphere (sphere of water)- oceans, lakes, seas
Lithosphere (sphere of rock)- crust, mantle Biosphere (sphere of
life)- all living things Process of movement: Carbon Cycle Photo

Slide 4
The Carbon Cycle Carbon Cycle- circulation of carbon atoms
through various processes Carbon circulates between Water and air
Air and ground Air and living things Living things and ground Image

Slide 5
Carbon Cycle: Water and Sky Carbon in the air: CO 2 gas Dense;
stays close to ground/sea level How it gets into water: Uptake CO 2
absorbed by bodies of water Colder water- more CO 2 can be absorbed
Question: whats happening to ocean temperatures? Image obtained

Slide 6
Carbon Cycle: Water and Sky Carbon in the water: CO 2 gas
Trapped in bubbles in water How it gets into air: Release CO 2
moves up to surface, freed Warmer water- more CO 2 gets released

2 uptake CO 2 release
Slide 7
Carbon Cycle: Earth and Sky Carbon in the mantle: CO 2 gas How
CO 2 gets into air: Eruptions Volcanoes- release lots of CO 2 into
atmosphere Image obtained from:

Slide 8
Carbon Cycle: Earths Breathing Life Carbon in the air: CO 2 gas
How it gets into organisms: Photosynthesis Plants store carbon as
sugars Food web: consumers eat producers, those consumers get
eaten, etc. Organisms use sugars to form carbon compounds Image

Carbon Cycle: Earths Breathing Life Carbon in organisms: carbon
compounds How it gets into the air: Respiration, Decomposition
Exhaling releases CO 2 gas into atmosphere Organisms die,
decompose; bacteria & fungi release CO 2 gas Image obtained

Slide 10
Carbon Cycle: Fossil Fuels Carbon in organisms: carbon
compounds How it gets into the ground: Fossilization Formed from
dead organisms Very particular conditions for dying Cannot be
exposed to air Submerged and/or buried shortly after death Buried
matter compacted by weight of soil above it High temperature,
pressure forms fossil fuels Image obtained from:

Slide 11
Carbon Cycle: Fossil Fuels Fossil Fuels Coal Oil Natural gas
Take millions of years to form Older fuel- more carbon stored per
unit of volume Image obtained from:
http://www.wired.com/images_blogs/wiredscience/2010/01/coal_f.jpg
Problems With Carbon Cycle Ocean temperatures rising Less CO 2
uptake, more CO 2 release Human influence Consuming fossil fuels
Changes stored carbon compounds into CO 2 gas Deforestation Less
photosynthesis; less CO 2 removed from atmosphere Less organisms to
be fossilized Image obtained from:
