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






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






3. Difference between high and low tide






4. Volcanoes - hot springs - geysers






5. Burning wood






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






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






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






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






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






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






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






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






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






15. 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






16. Off shore wind is the most efficient






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






18. Hard coal - highest rank - 96% carbon






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






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






21. Burning rubbish/garbage






22. Bacteria ferments biomass with sugars






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






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






25. Compacting biomass through high temperatures - VED goes up






26. Solar energy heats water which turns a turbine






27. Crops and crop residue






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






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






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






31. Water conservation - jobs - energy -






32. Burning to get heat and electricity






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






34. Replenish themselves or are continuously present






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






36. Volumetric energy density






37. Accumulation of organic material by living things






38. Solar cells to convert solar energy directly to electricity






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






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






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






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






43. Pockets of hot water/steam underground






44. Hydrogen sulfide pollution - sources are often national treasures






45. Semi-permeable dams






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. Burning biomass






48. Soft coal - reduced water (3%)






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






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