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. Whats it made of?
• 48. Earths Resources
• 49. Worksheet 4.1
• Keywords
• Renewable
• Nonrenewable
• Fossil fuel
• Ore

Earths 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-gt lignite -gt bituminous-gt 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 worlds population
• US consumes 30 of energy resources
• 90 of energy in US is from fossil fuels
