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. Burning rubbish/garbage






2. Off shore wind is the most efficient






3. Pockets of hot water/steam underground






4. Water conservation - jobs - energy -






5. Solid biomass to liquid biomass with chemicals and heat






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






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






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






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






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






11. Semi-permeable dams






12. Bacteria ferments biomass with sugars






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






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






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






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






17. Burning wood






18. Crops and crop residue






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






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






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






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






23. 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






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






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






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






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






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






29. Difference between high and low tide






30. Soft coal - reduced water (3%)






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






32. Burning to get heat and electricity






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






34. Volumetric energy density






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






36. Volcanoes - hot springs - geysers






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






38. Solar energy heats water which turns a turbine






39. Accumulation of organic material by living things






40. Replenish themselves or are continuously present






41. Solar cells to convert solar energy directly to electricity






42. 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






43. Burning biomass






44. Hard coal - highest rank - 96% carbon






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






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






47. Heat is recovered as steam or hot water to create electricity or heat buildings






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






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






50. Compacting biomass through high temperatures - VED goes up
