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






2. Soft coal - reduced water (3%)






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






4. 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






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






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






7. Burning wood






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






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






10. Crops and crop residue






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






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






13. Pockets of hot water/steam underground






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






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






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






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






18. Volumetric energy density






19. Off shore wind is the most efficient






20. Difference between high and low tide






21. Solar energy heats water which turns a turbine






22. Accumulation of organic material by living things






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. Hydrogen sulfide pollution - sources are often national treasures






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






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






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






28. Solar cells to convert solar energy directly to electricity






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






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






31. Semi-permeable dams






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






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






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






35. Burning to get heat and electricity






36. Burning rubbish/garbage






37. Hard coal - highest rank - 96% carbon






38. Volcanoes - hot springs - geysers






39. Bacteria ferments biomass with sugars






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






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






42. Solid biomass to liquid biomass with chemicals and heat






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






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






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






46. Burning biomass






47. Water conservation - jobs - energy -






48. Replenish themselves or are continuously present






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






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