Traditional Sources of Energy Essential Question How do humans being acquire and utilize sources of energy? 1. What are traditional fuel? tree Wood Peat Coal Moss Buried under sedimentary rocks with intense pressure by weight. Formed 300 mya 2.How is coal formed? tree Wood Peat Coal Moss Buried under sedimentary rocks with intense pressure by weight. Formed 300 mya 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. 3. How is Peat formed? Peat forms when plants in marshy areas is not totally carbonized. Peat has the potential to become coal. Sphagnum Moss Most peat is from Sphagnum moss. Peat Cutter Burning Peat 4. What is Coal? non renewable source of energy Coal forms from the accumulation and preservation of plant materials, usually in a swamp environment. This what they mined in the movie “October Sky”. Coal Coal Mine in the movie “October Sky” 5. What are the two types of nuclear energy? Alternative Non‐Renewable Energy 6. What is Nuclear Fusion? Nuclear fusion in the CORE of the Sun provide us Solar Energy! Nuclear fusion is an atomic reaction that fuels stars. In fusion, Hydrogen nuclei combine together to make Helium and produce Energy. Solar Energy is Renewable energy. Sunlight is used as energy for photosynthesis Oxygen CO2 Food Water 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 Nuclear power vs. Coal power Water vapor Uranium‐fuel of nuclear power plant Radiation danger Carbon dioxide is a greenhouse gas Coal‐fuel of coal plant Nuclear Fission Nuclear Fusion Worldwide nuclear power Powers the stars and plants near earthquake nuclear bombs. zones. Fuel: Hydrogen Fuel: Uranium Atomic Bomb dropped in Horoshima and Nagasaki, Japan http://www.weather.gov.hk/education/dbcp/pow_stat/eng/r5.htm Nuclear Bomb tested 450 x or more stronger than the atomic bomb. 8. Give examples of fossil fuels. 1. Natural gas (cleanest) 2. Oil or Petroleum 3. Coal Fossil fuels are Non renewable 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. Natural Gas 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. 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. 11. What are the advantages and disadvantages of using alternative renewable energy? Nuclear power is alternative source of energy but it is non‐ renewable. Alternative Energy creates less Pollution compared to fossil fuel. Alternative Energy Dependent on nature. Not always available. Fossil Fuel But fossil fuels are MORE convenient to use. 12. Of the following, which energy source produces the least amount of solid waste? A. coal B. natural gas C. oil D. peat 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 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. 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. 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. 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 Coal is a non renewable 17. ______ 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”. Oil 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. Natural gas 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. Nuclear fission 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. Wood 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. Peat 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. Nuclear fusion 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. Solar energy 24. _________________ is energy from the Sun. It is a renewable type of energy. Nuclear fission 25. _______________ is an alternative source of energy but a non‐renewable resource.
