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. Resevoir - dam - penstock - turbine - generator - outflow - inflow






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






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






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






5. Solid biomass to liquid biomass with chemicals and heat






6. 3 factors that affect volatility






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






8. Wood - crops grown for energy - crop residues - animal waste - algae - some garbage






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






10. Semi-permeable dams






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






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






13. Pockets of hot water/steam underground






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






15. Compacting biomass through high temperatures - VED goes up






16. Hard coal - highest rank - 96% carbon






17. Burning rubbish/garbage






18. Solar energy heats water which turns a turbine






19. Burning biomass






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






21. Water conservation - jobs - energy -






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






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






24. Hydrogen sulfide pollution - sources are often national treasures






25. Burning wood






26. Solar cells to convert solar energy directly to electricity






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






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






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






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






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






32. Replenish themselves or are continuously present






33. Volumetric energy density






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






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






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






37. Off shore wind is the most efficient






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






39. 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






40. Difference between high and low tide






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






42. Burning to get heat and electricity






43. Volcanoes - hot springs - geysers






44. Soft coal - reduced water (3%)






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






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






47. Bacteria ferments biomass with sugars






48. 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






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






50. Changes landscape - land reclamation - acid min drainage - black lung - foundation damage (subsidence) - mountain top removal - insurance - most danger
