1. Nonrenewable Resources

2. 4 nonrenewable resources: Coal Oil Natural gas Nuclear power

3. How fossil fuels form: 1.organisms decay in anaerobic conditions 2. Pressure over millions of years Ex: plants die in a swamp, and are covered with sediment, forming coal

4. Coal facts: Provides 25% of the world’s energy US and China are the leading producers Coal’s advantage over other fossil fuels: Abundant, cheap, easily processed, easily transported

5. 2 types of coal: Anthracite coal “hard “coal highest energy value Lower sulfur content so less polluting expensive Bituminous coal “soft” coal High sulfur content, gives off more pollutants Abundant cheap

6. Burning coal produces: Carbon dioxide which causes climate change Sulfur dioxide and nitrogen oxides which cause acid rain

7. Environmental hazards of mining: 1.Mercury – present in trace amounts in coal may be released when coal is burned causes brain damage 2. Particulate matter- soot released when coal is burned triggers respiratory problems and asthma

8. 3. Acid Drainage – surface mining exposes acids and toxic metals which contaminate waterways

9. Methods of mining coal: 1.Subsurface (underground) mining 2.Strip mining 3.Mountaintop removal
