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






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






4. Soft coal - reduced water (3%)






5. Crops and crop residue






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






7. Off shore wind is the most efficient






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






9. Burning biomass






10. Accumulation of organic material by living things






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






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






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






14. Hard coal - highest rank - 96% carbon






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






16. Pockets of hot water/steam underground






17. Bacteria ferments biomass with sugars






18. Replenish themselves or are continuously present






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






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






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






22. Hydrogen sulfide pollution - sources are often national treasures






23. Solid biomass to liquid biomass with chemicals and heat






24. Water conservation - jobs - energy -






25. 3 factors that affect volatility






26. Solar energy heats water which turns a turbine






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






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






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






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






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






32. Volcanoes - hot springs - geysers






33. Solar cells to convert solar energy directly to electricity






34. 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






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






36. Difference between high and low tide






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






38. 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






39. Burning wood






40. Semi-permeable dams






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






42. Burning to get heat and electricity






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






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. Bacteria break down with without oxygen - product is LFGs






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






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






49. Compacting biomass through high temperatures - VED goes up






50. Burning rubbish/garbage
