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. 3 factors that affect volatility






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






3. Solar energy heats water which turns a turbine






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






5. Water conservation - jobs - energy -






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






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






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






9. Burning rubbish/garbage






10. Pockets of hot water/steam underground






11. Solid biomass to liquid biomass with chemicals and heat






12. Difference between high and low tide






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






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






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






16. Volumetric energy density






17. 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






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






19. Replenish themselves or are continuously present






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






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






22. Solar cells to convert solar energy directly to electricity






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






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






25. Hard coal - highest rank - 96% carbon






26. Volcanoes - hot springs - geysers






27. Accumulation of organic material by living things






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






29. Off shore wind is the most efficient






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






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






32. Burning wood






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






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






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






36. Burning to get heat and electricity






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






38. Semi-permeable dams






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






40. Soft coal - reduced water (3%)






41. Crops and crop residue






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






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






44. 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






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






46. Hydrogen sulfide pollution - sources are often national treasures






47. Bacteria ferments biomass with sugars






48. Compacting biomass through high temperatures - VED goes up






49. Burning biomass






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