Fossil Fuels5-2Pgs. 111-117
  • 2/12/15 IN What are three renewable resources,
    and three non-renewable resources? Can you name
    a renewable resource that we use faster than it
    can be renewed?

2
Terms and Objectives
  • TERMS
  • ENERGY RESOURCE FOSSIL FUEL PETROLEUM
    NATURAL GAS COAL STRIP MINING ACID
    PRECIPITATION SMOG
  • OBJECTIVES
  • Classify the different forms of fossils
  • Explain how fossil fuels are obtained

3
Where do humans get useful energy?
  • Energy Resources natural resources that humans
    use to produce energy.

4
Remember
  • There are many types of renewable and
    nonrenewable energy resources and all of the
    energy released from these resources ultimately
    comes from the sun.

5
Where do humans get useful energy?
  • The energy resources on which humans currently
    depend the most are fossil fuels.

6
What are fossil fuels?
  • Fossil Fuels nonrenewable energy resources that
    form in the Earths crust over millions of years
    from the buried remains of once-living organisms.

7
How do fossil fuels work?
  • Energy is released from fossil fuels when they
    are burned.
  • There are many types of fossil fuels, which exist
    as liquids, gases, and solids, and humans use a
    variety of methods to obtain and process them
    which can sometimes have negative effects on the
    environment.

8
Liquid Fossil Fuels
  • Petroleum crude oil, an oily mixture of
    flammable organic compounds from which liquid
    fossil fuels and other products, such as asphalt,
    are separated.

9
What is separated from petroleum?
  • Gasoline
  • Jet Fuel
  • Kerosene
  • Diesel Fuel
  • Fuel Oil

10
Gaseous Fossil Fuels
  • Natural Gas a gaseous fossil fuel.
  • Most natural gas is used for heating and for
    generating electricity.

11
Components of Natural Gas
  • Methane
  • Fuel
  • Butane
  • Fuel for camp stoves
  • Propane
  • Heating fuel and as a cooking fuel

12
Solid Fossil Fuels
  • Coal a solid fossil fuel formed underground
    from buried, decomposed plant material.

13
Importance of Coal
  • Coal , the only fossil fuel that is a rock, was
    once the leading source of energy in the United
    States.
  • People burned coal for heating and transportation.

14
How do petroleum and natural gas form?
  • All fossil fuels form from the buried remains of
    ancient organisms.

15
How does coal form?
  • Coal forms underground over millions of years
    from decayed swamp plants.

16
  • The higher the carbon content, the cleaner the
    material burns.

17
Where are fossil fuels found?
18
How do humans obtain fossil fuels?
  • Drilling

19
How do humans obtain fossil fuels?
  • Strip mining

20
Problems with Coal
  • People began to use coal less because burning
    coal often produces large amounts of air
    pollution and because better energy resources
    were discovered.

21
Problems with Coal
  • Acid precipitation
  • Rain or snow that has a high acid content due to
    air pollutants.

22
Problems with Coal
  • Coal Mining can be hazardous to those who are
    working them, they can lower water tables,
    pollute the water supplies, and cause the
    overlying earth to collapse.

23
Problems with Petroleum
  • Oil Spills

24
Problems with Fossil Fuels
  • Smog a photochemical fog produced by the
    reaction of sunlight and air pollutants.

25
Dealing with Fossil Fuel Problems
  • Car pool
  • Use mass transit systems
  • Use alternative energy resources

26
  • OUT What are the three basic types of fossil
    fuels?
