1. Lesson 6.1 Fossil Fuels

2. Describe how fossil fuels are formed (S11/12ES-Id-10) . At the end of this lesson, the given DepEd learning competency should be met by the students.

3. Describe how fossil fuels are formed. Distinguish between the forms of fossil fuels. Identify the advantages and disadvantages of using fossil fuels.

4. Look around your house and observe your furniture, your utensils and your appliances. What material is it commonly made of?

5. Most materials we have at home are either made entirely or partially of plastic.

6. Plastics are made from fossil fuels . Different forms of fossil fuels undergo a complex process for it to turn into the plastic we are familiar with.

7. But where do fossil fuels come from? What are the advantages and disadvantages of using fossil fuels in the long run?

8. general term used to refer to all deposits of organic materials capable of being burnt as fuels comes in the form of: coal oil and gas Fossil Fuels How fossil fuels form

9. Coal is a carbon-rich deposit formed from dead plant material through the process of coalification . Forms of Fossil Fuels Coal

10. Peat is a precursor to coal formed through peatification or partial decay of plant debris in swampy, waterlogged environments. Forms of Fossil Fuels Peat

11. organic materials are buried in swamp environments burial results to formation of peat greater burial results to formation of lignite burial and metamorphism results to the formation of anthracite Process of Making Coal The formation of coal from peat as precursor to anthracite

12. Lignite lowest rank brown in color earthy, crumbly texture Ranks of Coal Lignite coal

13. Sub-bituminous coal “black lignite” in between lignite and bituminous coal Ranks of Coal Bituminous coal

14. Bituminous coal medium-rank coal black, shiny and hard Ranks of Coal Bituminous coal

15. Anthracite highest coal rank shiny and conchoidal fracture requires very deep burial, tectonic, and contact metamorphism Ranks of Coal Anthracite

16. Oil also known as petroleum . a black, thick, and mushy liquid commonly found between rock layers a well is dug to obtain it Forms of Fossil Fuels An oil well pumping up petroleum to the surface of the Earth.

17. Natural gas is made out of methane . pumped on wells and transported to large pipeline described as the cleanest energy alternative Forms of Fossil Fuels Natural gas pipeline

18. In 2013, 61.25% of energy consumption in the Philippines relies on fossil fuels. Power plants rely on fossil fuels to power up their equipments. Use of Fossil Fuels Fossil fuel power plant

19. Use of Fossil Fuels Advantages abundant easy to find very efficient easy to transport Disadvantages causes air pollution cannot be renewed in a short period of time

20. Fossil fuels Fossil fuel refers to all organic deposits capable of being burnt as fuel. The different forms of fossil fuel include coal, oil and natural gas. Coal Coal is a carbon-rich deposit formed from dead plant material which underwent the process of coalification. Peat is considered as a precursor to coal. Oil and Natural gas Oil is a black, thick, mushy liquid which is also known as petroleum , while natural gas is a made out of methane and the lightest hydrocarbon.
