DATING ROCKSDATING ROCKS• Radioactive isotopes-halflife• Older rocks below younger(superpoisition)• fossils
• Layer 2 is younger than layer 5• Layer 6 is younger than layer 2 but older than
1
FOSSILSFOSSILS• 3000 years old• Trace fossils • Resin• Palentologists-study fossils• Organism- water and sand
ELECTRICITYELECTRICITY• Coal is largest source of generating• Hydropower• Nuclear• Natural gas
COALCOAL• Peat, lignite, bitumen, anthracite• Fossil fuel• Non renewable• Cheap• Air pollution, water• Habitat destruction• Mtn top mining• Open pit mining• Strip mining
TAR SANDSTAR SANDS• Canada• Keystone Pipe lineBitumen• Texas• Environmental concerns• Oil spill• Agriculture• Heat• Lots of h2o and energy
FRACKINGFRACKING• Pumping of water sand and bad chemicals• Materials get in water, natural gas• Region called-Marcellus Shale
MOUNTAIN TOP MININGMOUNTAIN TOP MINING• Dest of ppl homes• Coal• Pollution• BAD water• Flooding• Chemicals pressure
CARBON DIOXIDECARBON DIOXIDE• Global warming• Burning of fossils fuels• CO2
NATURAL GASNATURAL GAS• Use to generate elec• Cheap• GHG• Fracking is used to get• Found with oil• hydrocarbon
NONRENEWABLE NONRENEWABLE ENERGY SOURCESENERGY SOURCES
• Fossil fuels• Tar sand, biomass(trees), oil shale
FOSSIL FUELSFOSSIL FUELS• Oil gas coal non renew• Remains of organic material
OILOIL• 6000 products• Natural gas• Drilling
