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






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






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






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






6. Hard coal - highest rank - 96% carbon






7. Solar cells to convert solar energy directly to electricity






8. Water conservation - jobs - energy -






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






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






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






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






13. Volumetric energy density






14. Crops and crop residue






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






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






17. Replenish themselves or are continuously present






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






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






20. Burning wood






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






22. Solar energy heats water which turns a turbine






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






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






25. Semi-permeable dams






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






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






28. 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






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






30. Bacteria ferments biomass with sugars






31. Hydrogen sulfide pollution - sources are often national treasures






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






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






34. Off shore wind is the most efficient






35. 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






36. Burning biomass






37. Pockets of hot water/steam underground






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






39. Soft coal - reduced water (3%)






40. 3 factors that affect volatility






41. Solid biomass to liquid biomass with chemicals and heat






42. Burning to get heat and electricity






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






44. Burning rubbish/garbage






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






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






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






48. Difference between high and low tide






49. Compacting biomass through high temperatures - VED goes up






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