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. 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






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






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






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






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






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






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






8. Accumulation of organic material by living things






9. Volumetric energy density






10. Difference between high and low tide






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






12. Water conservation - jobs - energy -






13. Burning wood






14. 3 factors that affect volatility






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






16. Off shore wind is the most efficient






17. Burning biomass






18. Burning rubbish/garbage






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






20. Pockets of hot water/steam underground






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






22. Replenish themselves or are continuously present






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






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






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






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






27. Hard coal - highest rank - 96% carbon






28. Soft coal - reduced water (3%)






29. Compacting biomass through high temperatures - VED goes up






30. Bacteria ferments biomass with sugars






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






32. Solar cells to convert solar energy directly to electricity






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






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






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






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






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






38. Hydrogen sulfide pollution - sources are often national treasures






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






40. Semi-permeable dams






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






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






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






44. Crops and crop residue






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






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






47. Solar energy heats water which turns a turbine






48. Solid biomass to liquid biomass with chemicals and heat






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






50. 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
