Renewable And Nonrenewable Energy

Subject : science
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Burning to get heat and electricity






2. Bacteria ferments biomass with sugars






3. Secondary pollution (toxic materials and alcohols - blocking the sun for some animals) - bird death ray - startup cost






4. Burning biomass






5. Finite supply being used faster than they can be replenished






6. Remains of once living organisms preserved and altered by geological forces






7. Water floods - peat and sediment is pushed down - peat is pressed down for millions of years - coal is formed






8. Easy to store - 90% of world's commercially traded energy is oil/natural gas - secondary recovery - cracking - profitable - jobs - natural gas = no air pollution






9. Secondary Pollution -Toxic materials and alcohols -Blocking the sun for some animals -No direct pollution though! Bird death ray - Startup cost






10. Near the poles - tight openings - high tidal range






11. Heat is recovered as steam or hot water to create electricity or heat buildings






12. Effecting the tide - high startup cost - low efficiency in some cases






13. Volumetric energy density






14. High tidal range - mouths of bays and estuaries - ideally near poles






15. Accumulation of organic material by living things






16. Crops and crop residue






17. Semi-permeable dams






18. Compacting biomass through high temperatures - VED goes up






19. Slow decay of radioactive particles in rocks gives off heat






20. Naturally occurring substance that can potentially be extracted using modern technology






21. Lowest rank coal - less water and higher proportion of burnable materials than peat (40% water)






22. 3 factors that affect volatility






23. Microscopic dying organisms sink to the bottom of the ocean secreting drops of oil - shale is formed from mud and sediment with oil droplets - over time the droplets rise into a pocket in the ground






24. Organic materials are changed to lighter - more volatile hydrocarbons






25. Energy that can be obtained from movement of water due to the gravitational pull of the sun - moon - and earth's rotation






26. Off shore wind is the most efficient






27. Same as pyrolysis process but with more heat and less gas - goes all the way to gas






28. Bacteria break down with without oxygen - product is LFGs






29. Solar cells to convert solar energy directly to electricity






30. Hydrogen sulfide pollution - sources are often national treasures






31. Difference between high and low tide






32. Hard coal - highest rank - 96% carbon






33. Burning rubbish/garbage






34. Air cools more quickly over land than water - wind cycle goes the opposite way as day winds






35. Volcanoes - hot springs - geysers






36. Unreliable - energy companies only see it as supplemental power - strong winds are usually not near people or grids






37. Radiant energy form the sun heats earth and atmosphere - causes warming of the air and wind cycle






38. Adding hydrocarbons by breaking down non-useful parts of oil






39. Solar energy heats water which turns a turbine






40. Air is heated from ground - warm air flows upward - cold air replaces it






41. Solid biomass to liquid biomass with chemicals and heat






42. Soft coal - reduced water (3%)






43. Solar radiation from the sun is converted to heat or electricity






44. Replenish themselves or are continuously present






45. Hard to transport - natural gas needs to be changed into a liquid to be efficiently transported - drill sites could be terrorist targets - disorients whales - harms the environment - hard to find/pump - dangerous - oil air pollution






46. Pockets of hot water/steam underground






47. Air heated more from ground near equator - creates global jet streams






48. Known deposits which can be extracted from profitably using modern technology under certain economic conditions






49. Water conservation - jobs - energy -






50. Burning wood
