1. Energy Resources

2. Fossil Fuels
Fossil Fuel- a nonrenewable energy source formed from remains that lived long ago
Types of fossil fuels
Petroleum (also known as oil)
Natural Gas
Coal

3. Fossil Fuels How do they form?
Petroleum and natural gas- form from remains of microscopic sea organisms and settle on ocean floor. Takes millions of years
Coal formation- pressure and heat cause changes in the remainder of swamp plants. First it is peat, then hear and pressure are applied and carbon content increases

4. Fossil Fuels Problems with fossil fuels
Coal mining-creates environmental problems, coal mines could collapse
Acid precipitation-precipitation such as rain, snow, or sleet with a high acid concentration because of pollution against atmosphere.
Smog- haze that forms when sunlight acts on industrial pollutants

5. Alternative Resources
Nuclear Energy- energy released by a fission or fusion reaction
Fission- process where nuclei of radioactive atoms are split into two or more
Fusion- joining of two or more nuclei

6. Alternative Resources
Chemical Energy- released when a chemical compound reacts to produce new compounds
Solar Energy- received by the earth from the sun in form of radiation
Wind power- use of a windmill to drive an electric generator
Hydroelectric energy- electrical energy produced by falling water

7. Alternative Resources
Biomass- organic matter that can be a source of energy
Gasohol- a mixture of gasoline and alcohol that is used as a fuel
Geothermal energy- produced by heat within the earth
