Conversions: 1 gallon of gasoline = 132 MJ 1 kWh = 3.6 MJ 1 metric ton of coal = 29,300 MJ1 liter diesel fuel = 36 MJ Fossil Fuels Fossil fuels are produced by geological processes acting on organic matter over long periods of time (hundreds of millions of years). Fossil Fuels 1. What are the four factors that determine which type of fossil fuel forms? 2. What are some uses of fossil fuels? 3. What do fossil fuels release when they are burned? Coal 1. How does coal form? 2. How do we extract coal from the ground? 3. What are some ways we use coal? 4. What are some problems with using coal? Coal Formation Coalification Water is expelled as peat is compacted. Plant material breaks down releasing natural gas (mostly methane). A bed of peat about 10 feet thick produces a layer of coal about 1 foot thick. Oil (Petroleum) 1. How does oil form? 2. How do we extract oil from the ground? 3. What are some ways we use oil? 4. What are some problems with using oil? Oil (Petroleum) and Natural Gas Formation  Compare and Contrast the Formation of Oil vs Coal Move the statements from this slide to the appropriate place on the diagram on the next slide.
