Fossil fuels Presentation Transcript

  • 1.  
  • 2. Objectives
    • Identify the three types of fossil fuels
    • Relate the three types of fossil fuels to where they are used everyday
    • Discuss the origin and characteristics of the three main types of fossil fuels
    • Discuss ideas for the conservation of fossil fuels
  • 3. What are the three types of fossil fuels?
    • Petroleum
    • Natural Gas
    • Coal
  • 4. How were fossil fuels formed?
    • Dead plants and animals
      • Covered with layers of mud, mud, volcanic ash, and other things collected on the earth’s surface
      • Happens over many years through great pressure, heat, and bacteria
  • 5. Petroleum
    • Petroleum (hydrocarbons) must be separated to make use of their energy
    • Separated by a process called fractional distillation
    • Certain petroleum substances boil at specific temperatures and can be removed at those temperatures
      • Gasoline: between 40-180 C, asphalt: between 405-515 C
  • 6. Natural Gas
    • Usually found in the same places as petroleum under the surface of the earth
    • Made mostly of methane (CH 4 )
    • Used for things like gas stoves or gas heating for homes
  • 7. Coal
    • Solid fossil fuel made from the remains of plants
    • Found by mines, sometimes at the earth’s surface, but usually about 100 meters underground
      • Lackawanna Coal Mine near Scranton
    • Must be cleaned and purified before using it as a fuel
  • 8. Dangers
    • Petroleum: when it is burned, it produces CO
      • Dangerous, odorless gas
    • Natural Gas: when it is burned, it produces CO 2
      • One of the key components that warms the earth’s atmosphere
    • Coal: if not cleaned properly, can cause acid rain
      • Can contaminate water sources and be dangerous if you have too much of it
  • 9. Conservation
    • All fossil fuels are non-renewable resources
      • They cannot be replaced after they are used
    • It is possible that the United States will run out of petroleum within the 100 years
  • 10. What are some things that we can do to save our fossil fuels?
