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






2. Crops and crop residue






3. Pockets of hot water/steam underground






4. Burning wood






5. Volumetric energy density






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






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






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






9. Bacteria ferments biomass with sugars






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






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






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






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






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






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






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






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






18. Water conservation - jobs - energy -






19. 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






20. Semi-permeable dams






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






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






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






24. Solar cells to convert solar energy directly to electricity






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






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






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






28. Solar energy heats water which turns a turbine






29. Replenish themselves or are continuously present






30. 3 factors that affect volatility






31. Difference between high and low tide






32. Burning rubbish/garbage






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






34. Hard coal - highest rank - 96% carbon






35. Compacting biomass through high temperatures - VED goes up






36. Burning to get heat and electricity






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






38. Hydrogen sulfide pollution - sources are often national treasures






39. Off shore wind is the most efficient






40. Volcanoes - hot springs - geysers






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






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






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






44. Solid biomass to liquid biomass with chemicals and heat






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






46. 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






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






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






49. Soft coal - reduced water (3%)






50. Burning biomass
