2.  Hematite- used to make steel  Galena- used in car batteries and to solder  Gold, Silver, Platinum- used in electronics and dental work  Chalcopyrite- used as wiring in coins jewerly and as building ornamens  Sphalerite- used in making brass and dalvanized steel  Diamond- used in drill bits and saws  Graphite- used in pencils, paints, lubricants, andbatteries  Calcite- used in cement; as building stone  Halite- used in food  Kaolinite- used in ceramics, cement, and bricks  Quartz- used as glass  Sulfur- used in gunpowder, medicines, and rubber  Gypsum- used in plaster and wallboard

3. Nonrenewable EnergyRenewable Energy Can’t use again Natural resources Takes millions of years to form Coal Natural gas Releases carbon dioxide Petroleum Most abundant fuel Pollutes the atmosphere Able to reuse Geothermal Solar Hydroelectric Biomass Wind Clean energy Not widely used

4.  Coal- remains of plants that have gone through carbonization  Petroleum- (oil) moicroorganisms & plantsburied by sediment changing over millions of years due to heat & pressure  Natural Gas- moicroorganisms & plants buried by sediment changing over millions of years due to heat & pressure  Peat- partial decomposition of plants  Lignite- peat buried by other sediments, formed when heat & pressure increase  Bituminous Coal- increased temp. & pressure to change from lignite, 80% carbon  Anthracite- high temp & pressure need to change from Bituminous

5. ProsCons Abundantly used Large abundance Produce almost every product Coal is most abundant Can not be reused Takes millions of years to form Creates pollution Amount decreasing

6. FusionFission Nuclei of hydrogen combined Temps. Of more that 15,000,000C 40 years tried to harvest energy Waste less dangerous Splitting of nucleus 1 million x stronger than strongest chemical bonds Generates energy Nuclear reactor Only uranium-235 is used Water used to cool No fossil fuels
