1 Natural Resources Renewable –Resource that has the ability to renew itself over a relatively short period of time and can last as long as the Earth. Plants Animals Surface water Soil Sunshine

2 Renewable Resources Renewable Resources can be considered Non-Renewable when: –Animals become extinct. –Droughts & Chemical Spills – groundwater –Pollution – oxygen supply, trees, animals, soil

3 Natural Resources Nonrenewable –Resources that cannot be replenished by nature within our lifetimes, and therefore are in limited supply. Fossil Fuels Metals Minerals

4 Fossil Fuels Any hydrocarbon that may be used as a source of energy Formed from organic matter (plants and animals) which were buried millions of years ago. Over time, the pressure of the massive weight of rock and mud which covered the organic matter created heat, which changed this matter over a period of several hundred million years –coal (remains of ancient swamps and forests) –oil (remains of ancient marine organisms) –natural gas – less dense than water (rises)

5 Oil Trap A geologic structure that allows large amounts of fluid to accumulate –Permeable reservoir –Impermeable cap preventing migration of fluids up

6 Alternative Energy Resources Tar Sands –Clay, sand, water, black tar mixture –Requires energy to refine – ½ of what is produced Oil Shale –Contains kerogen (waxy hydrocarbon) –Unprofitable solution (1/8 heat energy of crude oil)

7

8 Formation of Mineral Deposits Igneous Processes –Gold, silver, copper, mercury, lead, platinum, nickel Hydrothermal Solutions (hot water) –Ore deposits –Gold, lead, zinc, silver, copper

9 Michigan’s Natural Resources Non-renewable –Peat –Calcium chloride –Iron ore –Cement –Sand and Gravel –Salt –Natural gas –Gypsum –Limestone –Oil Renewable –Animals –Surface water –Trees –soil
