Plant deposits covered by sediments that squeezes out the water and gases. 3. Lignite is denser deposits of peat. 1. Also known as brown coal 4. Bituminous is a more compressed lignite 1. Also known as soft coal 2. It is 80 to 90 percent carbon and produces great amounts of heat. 5. Petroleum and Natural Gas 1. Petroleum is oil 2. Natural gas is hydrocarbons in a gaseous state 3. Both form from microorganisms.

12. February 17, 2016February 17, 2016February 17, 2016 Notes Section 11.2 6. Formation of petroleum and natural gas 1. Microorganism accumulated on ocean and lake floors, then were covered by sediments. 2. Limited oxygen, heat and pressure cause a chemical changes covert the deposits into petroleum and natural gas. 7. Petroleum and Natural Gas deposits 1. Flow upward (due to pressure from sediments) through permeable rocks. 2. Flows upward until it encounters an impermeable rock (slate) called a cap stone. 3. A reservoir forms and the petroleum separates.

Crude oil is also used in petrochemical production; plastics, fabrics, medicines, tars, waxes, rubber, insecticides, fertilizers, detergents, and shampoos. 9. Fossil fuels supplies 1. Nonrenewable resource 2. 200 years of coal in reserve 3. 75% of oil in U.S. discovered 4. In some places 90% of oil still in the ground. 10. Fossil fuels and the environment 1. Causes acid rain, air pollution and oil spills harm oceans and wildlife.
