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






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






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






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






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






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






7. Bacteria ferments biomass with sugars






8. Burning to get heat and electricity






9. Replenish themselves or are continuously present






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






11. Hydrogen sulfide pollution - sources are often national treasures






12. Volumetric energy density






13. Burning rubbish/garbage






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






15. Off shore wind is the most efficient






16. 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






17. Semi-permeable dams






18. Solar energy heats water which turns a turbine






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






20. Volcanoes - hot springs - geysers






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






22. Solid biomass to liquid biomass with chemicals and heat






23. Accumulation of organic material by living things






24. Compacting biomass through high temperatures - VED goes up






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






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






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






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






29. Burning wood






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






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






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






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






34. Pockets of hot water/steam underground






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






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






37. Hard coal - highest rank - 96% carbon






38. Difference between high and low tide






39. Soft coal - reduced water (3%)






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






41. Water conservation - jobs - energy -






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






43. Burning biomass






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






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






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






47. 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






48. Solar cells to convert solar energy directly to electricity






49. 3 factors that affect volatility






50. Crops and crop residue
