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. Organic materials are changed to lighter - more volatile hydrocarbons






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






4. Volumetric energy density






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






6. Solar energy heats water which turns a turbine






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






8. 3 factors that affect volatility






9. Off shore wind is the most efficient






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






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






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






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






14. Accumulation of organic material by living things






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






16. Pockets of hot water/steam underground






17. Solid biomass to liquid biomass with chemicals and heat






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






19. Hard coal - highest rank - 96% carbon






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






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






22. Burning to get heat and electricity






23. Semi-permeable dams






24. Replenish themselves or are continuously present






25. Solar cells to convert solar energy directly to electricity






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






27. Burning wood






28. Difference between high and low tide






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






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






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






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






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






34. Crops and crop residue






35. Bacteria ferments biomass with sugars






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






37. Burning rubbish/garbage






38. Hydrogen sulfide pollution - sources are often national treasures






39. Soft coal - reduced water (3%)






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






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






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






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






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






45. Water conservation - jobs - energy -






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






47. Compacting biomass through high temperatures - VED goes up






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. Burning biomass






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