1. Fossil Fuels 2/10/15 5-2a pgs. 111-117 IN: What is the difference between renewable and nonrenewable resources? Put your DRW on the box

2.  Renewable Energy from the Sun Wind Water Wood Fruits and Vegetables Meat from animals  Nonrenewable Fossil Fuels Coal Petroleum (oil, gasoline) Natural Gas Rocks Minerals Metals Plastics

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 Earth’s 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.

10. 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.

11. What is separated from petroleum?  Gasoline  Jet Fuel  Kerosene  Diesel Fuel  Fuel Oil

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

13. Components of Natural Gas  Methane Fuel  Butane Fuel for camp stoves  Propane Heating fuel and as a cooking fuel

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

15. 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.

16. How do fossil fuels form?  All fossil fuels form from the buried remains of ancient organisms.

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

18.  The higher the carbon content, the cleaner the material burns.
