1 Warm- Up Take a seat and update your table of contents. Take a copy of Test 2 Most Missed and begin answering the questions. TOC: 46. Test 2 Most Missed 47. What’s it made of? 48. Earth’s Resources 49. Worksheet 4.1 Keywords: Renewable Nonrenewable Fossil fuel Ore

2 Earth’s Resources

3 Resources Renewable resource: can be replenished over a short amount of time Ex: food, natural fibers, trees; wind, solar, and hydro- power Nonrenewable resources: takes millions of years to form and accumulate Ex: coal, oil, natural gas, iron, copper, uranium, gold

4 Any hydrocarbon that may be used as a form of energy (coal, oil, natural gas) is a FOSSIL FUEL Electric plants use 70% of mined coal Coal burning increases acid rain. What other harmful affects exist?

5 Coal Coal: heat and pressure transform plant material Peat-> lignite -> bituminous-> anthracite (hard coal)

6 US Coal Fields

7 Oil and Natural Gas Form from remains of plants & animals buried in ancient seas. large amounts of remains become trapped in ocean sediments Chemical reactions transform remains into hydrocarbons Oil traps stack oil & gas on top of water due to density; anticlines

8 Alternative Fuels Tar Sands: mixtures of clay and sand with thick tar called bitumen Oil can not be pumped away easily Extracting and refining requires half of the energy gained! Oil Shale: rock with hydrocarbon kerogen Energy is only 1/8 of crude oil Unprofitable in common regions

9 Mineral Deposits Almost everything contains a derivative of or actual mineral Ore is a useful metallic mineral that can be mined for profit Some form as the result of igneous processes (heavy minerals crystallize from magma) and hydrothermal solutions (hot, metal- rich fluids after movement of magma

10 Placer Deposits Heavy minerals settle in moving water Gold!- largest found was 210 pounds

11 Nonmetallic Mineral Resources Desirable due to their properties (fluorite and limestone) 2 groups are building materials and industrial minerals See chart on page 101.

12 US is made up of 6% of the world’s population US consumes 30% of energy resources 90% of energy in US is from fossil fuels
