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 Missed47. What’s it made of?48. Earth’s Resources49. Worksheet 4.1Keywords:• Renewable• Nonrenewable• Fossil fuel• Ore
Earth’s Resources
ResourcesRenewable 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
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
Alternative FuelsTar 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
Mineral Deposits• Almost everything contains a derivative of or actual mineral• Ore is a useful metallic mineral that can be mined for profitSome form as the result of igneous processes (heavy minerals
crystallize from magma) and hydrothermal solutions (hot, metal- rich fluids after movement of magma
Placer Deposits
• Heavy minerals settle in moving water
• Gold!- largest found was 210 pounds
Nonmetallic Mineral Resources• Desirable due to
their properties (fluorite and limestone)
• 2 groups are building materials and industrial minerals
