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






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






3. 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






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






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






6. 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






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






8. Volumetric energy density






9. Solar cells to convert solar energy directly to electricity






10. Difference between high and low tide






11. Bacteria ferments biomass with sugars






12. Crops and crop residue






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






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






15. Compacting biomass through high temperatures - VED goes up






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






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






18. 3 factors that affect volatility






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






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






21. Burning to get heat and electricity






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






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






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






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






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






27. Water conservation - jobs - energy -






28. Replenish themselves or are continuously present






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






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






31. Volcanoes - hot springs - geysers






32. Solar energy heats water which turns a turbine






33. Soft coal - reduced water (3%)






34. Burning rubbish/garbage






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






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






37. Off shore wind is the most efficient






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






39. Hard coal - highest rank - 96% carbon






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






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






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






43. Burning wood






44. Hydrogen sulfide pollution - sources are often national treasures






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






46. Solid biomass to liquid biomass with chemicals and heat






47. Semi-permeable dams






48. Pockets of hot water/steam underground






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






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