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. Finite supply being used faster than they can be replenished






2. Volumetric energy density






3. Solid biomass to liquid biomass with chemicals and heat






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






5. Burning wood






6. Difference between high and low tide






7. Replenish themselves or are continuously present






8. Hard coal - highest rank - 96% carbon






9. Solar energy heats water which turns a turbine






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






11. Burning biomass






12. Solar cells to convert solar energy directly to electricity






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






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






15. 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






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






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






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






19. Hydrogen sulfide pollution - sources are often national treasures






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






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






22. Burning rubbish/garbage






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






24. Accumulation of organic material by living things






25. Soft coal - reduced water (3%)






26. 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






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






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






29. Burning to get heat and electricity






30. Water conservation - jobs - energy -






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






32. Semi-permeable dams






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






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






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






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






37. 3 factors that affect volatility






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






39. Bacteria ferments biomass with sugars






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






41. Compacting biomass through high temperatures - VED goes up






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






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






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






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






46. Off shore wind is the most efficient






47. Volcanoes - hot springs - geysers






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






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






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