Carbon and Energy
CARBON
found in: trees, diamonds, atmosphere, plastic
-
biochemical cycle: atmosphere= co2, hydrosphere= dissolved, lithosphere= limestone + ff, biosphere= living/used to be living
-

-
FLUXES
geological carbon cycle: slow, rocks + sediment, reservoir turnover rate= 100,000 years
biological carbon cycle:fast, vegetation, soils and atmosphere, turnover rate= few years to millenia
STORES
sedimentary carbonate rocks: shells + skeletons of marine creatures + planktons
when they die remains sink and accumulate and are buried by sediment
largest stores= Himalayas
biologically derived:
shale= organisms embedded in layers of mud
oil+gas= remains of organic matter deposited 320 million years ago
coal= remains of plants deposited in swampy areas
released=
volcanic outgassing= 300 million tonnes a year
volcanic eruptions at convergent + divergent + mid ocean ridge
chemical weathering= atmosphere-> lithosphere->hydrosphere->biosphere->lithosphere->atmosphere

HUMAN IMPACT
-
natural green house effect = neutral temp control system -> retain heat to prevent temps being -6 degrees
-

-
ENERGY PATHWAYS
-
gas and oil pipelines, sea routes, road rail, electricity cables
-
CHOKEPOINTS
narrow channels along widely used global sea routes
-> Suez Canal, panama
THREATS TO ENERGY PATHWAYS =
2009 somali = pirates hijacked tanker Indian Ocean + ransom 3 million
Russian takeover in Ukraine
mosul 2017 = 19 oil wells set on fire by terrrorists
ENERGY KEY PLAYERS
