Traditional Sources of Energy Eric Angat Teacher Slide 2 Essential Question How do humans being acquire and utilize sources of energy? Slide 3 Wood Peat Coal Formed 300 mya Buried under sedimentary rocks with intense pressure by weight. Moss tree 1. What are traditional fuel? Slide 4 Wood Peat Coal Formed 300 mya Buried under sedimentary rocks with intense pressure by weight. Moss tree 2.How is coal formed? Slide 5 Wood Wood is the primary source of energy in rural areas. This source of energy is from trees thus it is renewable. They burn this source of energy to cook and produce heat. Slide 6 3. How is Peat formed? Peat forms when plants in marshy areas is not totally carbonized. Peat has the potential to become coal. Slide 7 Sphagnum Moss Most peat is from Sphagnum moss. Slide 8 Peat Cutter Slide 9 Burning Peat Slide 10 4. What is Coal? Coal forms from the accumulation and preservation of plant materials, usually in a swamp environment. This what they mined in the movie October Sky. non renewable source of energy Slide 11 Coal Coal Mine in the movie October Sky Slide 12 Slide 13 1.Fusion 2.Fission Alternative Non-Renewable Energy 5. What are the two types of nuclear energy? Slide 14 6. What is Nuclear Fusion? Nuclear fusion is an atomic reaction that fuels stars. In fusion, Hydrogen nuclei combine together to make Helium and produce Energy. Nuclear fusion in the CORE of the Sun provide us Solar Energy! Solar Energy is Renewable energy. Slide 15 Sunlight is used as energy for photosynthesis Food Oxygen Water CO 2 Slide 16 7. What is Nuclear Fission? Fission is the splitting of a large atom like Uranium into two or more smaller ones and produce ENERGY. Fission reaction does not normally occur in nature. It is Non-Renewable Slide 17 Water vapor Carbon dioxide is a greenhouse gas Uranium-fuel of nuclear power plant Coal-fuel of coal plant Radiation danger Nuclear power vs. Coal power Slide 18 Nuclear Fusion Nuclear Fission http://www.weather.gov.hk/education/dbcp/pow_stat/eng/r5.htm Worldwide nuclear power plants near earthquake zones. Fuel: Uranium Powers the stars and nuclear bombs. Fuel: Hydrogen Atomic Bomb dropped in Horoshima and Nagasaki, Japan Nuclear Bomb tested 450 x or more stronger than the atomic bomb. Slide 19 Fossil fuels are Non renewable 1.Natural gas (cleanest) 2.Oil or Petroleum 3.Coal 8. Give examples of fossil fuels. Slide 20 9. What is Natural Gas? Natural gas is the cleanest burning fossil fuel, producing primarily carbon dioxide, water vapor and small amounts of nitrogen oxides. Natural gas is used extensively in residential for cooking and heating. Slide 21 The United States Department of Transportation (DOT) and California Public Utilities Commission (CPUC) rules and regulations regarding the odorizing of natural gas. For your protection, Gas companies add an odorant called MERCAPTAN to give natural gas a distinctive odor so leaks can be more readily detected. Natural Gas Slide 22 10. What is Oil or Petroleum? Oil is a non renewable source of energy made from the remains of ancient plants and animals, compressed deep in the earth. It is usually found in layers of sedimentary rocks. Slide 23 11. What are the advantages and disadvantages of using alternative renewable energy? Nuclear power is alternative source of energy but it is non- renewable. Slide 24 Alternative Energy creates less Pollution compared to fossil fuel. Fossil Fuel Alternative Energy But fossil fuels are MORE convenient to use. Dependent on nature. Not always available. Slide 25 12. Of the following, which energy source produces the least amount of solid waste? A.coal B.natural gas C.oil D.peat Slide 26 13. Why do green plants require solar energy? A. to produce their own food B. to absorb nitrogen into their roots C. to release carbon dioxide into the atmosphere D. to decompose the dead or decaying remains of animals Slide 27 14. Which describes the difference between nuclear fission and nuclear fusion? A.Nuclear fission is the process that produces the radiant energy of stars, and nuclear fusion splits a heavier nucleus into smaller nuclei. B. Nuclear fission splits a heavier nucleus into smaller nuclei, and nuclear fusion is the process that produces the radiant energy of stars. C. Nuclear fission produces the energy in the core of Earth, and nuclear fusion produces energy in nuclear power plants. D. Nuclear fission produces energy in nuclear power plants, and nuclear fusion produces the energy in the core of Earth. Slide 28 15. A company has several factories around the world and has decided to transition from burning fossil fuels to using alternative energy resources. How could a decrease in burning fossil fuels impact the atmosphere? A.It could decrease the oxygen levels of the atmosphere. B.It could increase the nitrogen levels of the atmosphere. C.It could decrease the carbon dioxide levels of the atmosphere. D.It could increase the sulfur dioxide levels of the atmosphere. Slide 29 16. Which is an advantage of safely using uranium as an energy source rather than using coal? A.Uranium produces energy without polluting the atmosphere, while burning coal can increase the CO2 in the atmosphere. B.Uranium reduces the amount of thermal pollution, while burning coal can increase the amount of thermal pollution. C.Uranium is the most cost-efficient energy resource, while coal is the most expensive energy resource. D.Uranium can be easily mined from deep within Earth, while coal is a hard resource to mine from deep within Earth. Slide 30 For 17-24: Use the following sources of energy as choices to complete the following ideas. nuclear fission ( 2x) wood peat coal oil nuclear fusion solar energy Natural gas Slide 31 17. ______ is a non renewable source of energy that forms from the accumulation and preservation of plant materials, usually in a swamp environment. This what they mined in the movie October Sky. Coal Slide 32 18. ________ is a non renewable source of energy made from the remains of ancient plants and animals, compressed deep in the earth. It is usually found in layers of sedimentary rocks. Oil Slide 33 19. ___________________ gas is the cleanest burning fossil fuel, producing primarily carbon dioxide, water vapor and small amounts of nitrogen oxides. Other fossil fuels are coal and oil. It is used extensively in residential for cooking and heating. Natural gas Slide 34 20. ____________________ is the splitting of an atom's nucleus creating two products of roughly half the mass of the original. This type of power generation, is used in both nuclear weapons and nuclear power plants. Nuclear fission Slide 35 21. ___________ is the primary source of energy in rural areas. This source of energy is from trees thus it is renewable. They burn this source of energy to cook and produce heat. Wood Slide 36 22. ______________________ is vegetable matter which has been partially carbonized due to the way in which it decomposes. Over time, these have the potential to evolve into coal. Peat Slide 37 23. ________________ is the joining of Hydrogen nuclei to create Helium and great amount of energy. This nuclear process is the one that powers the stars. Nuclear fusion Slide 38 24. _________________ is energy from the Sun. It is a renewable type of energy.
