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






2. Solar cells to convert solar energy directly to electricity






3. Water conservation - jobs - energy -






4. Solid biomass to liquid biomass with chemicals and heat






5. Pockets of hot water/steam underground






6. Difference between high and low tide






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






8. Hard coal - highest rank - 96% carbon






9. Soft coal - reduced water (3%)






10. 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






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






12. Compacting biomass through high temperatures - VED goes up






13. Burning biomass






14. Bacteria ferments biomass with sugars






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






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






17. Semi-permeable dams






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






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






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






21. Volumetric energy density






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






23. Volcanoes - hot springs - geysers






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






25. 3 factors that affect volatility






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






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






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






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






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






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






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






33. Hydrogen sulfide pollution - sources are often national treasures






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






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






36. Replenish themselves or are continuously present






37. Accumulation of organic material by living things






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






39. Crops and crop residue






40. Off shore wind is the most efficient






41. Burning to get heat and electricity






42. Solar energy heats water which turns a turbine






43. 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






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






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






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






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






48. Burning wood






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






50. Burning rubbish/garbage
