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






2. Off shore wind is the most efficient






3. Burning wood






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






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






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






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






8. Water conservation - jobs - energy -






9. 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






10. Compacting biomass through high temperatures - VED goes up






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






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






13. Pockets of hot water/steam underground






14. Burning rubbish/garbage






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






16. Hydrogen sulfide pollution - sources are often national treasures






17. Accumulation of organic material by living things






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






19. Crops and crop residue






20. Hard coal - highest rank - 96% carbon






21. Difference between high and low tide






22. Bacteria ferments biomass with sugars






23. Solid biomass to liquid biomass with chemicals and heat






24. Volumetric energy density






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






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






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






28. Semi-permeable dams






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






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






31. Burning biomass






32. Solar cells to convert solar energy directly to electricity






33. Volcanoes - hot springs - geysers






34. Burning to get heat and electricity






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






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






37. 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






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






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






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






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






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






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






44. Solar energy heats water which turns a turbine






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






46. Soft coal - reduced water (3%)






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






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






49. 3 factors that affect volatility






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