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. 3 factors that affect volatility






3. Accumulation of organic material by living things






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






5. Water conservation - jobs - energy -






6. 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






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






8. Off shore wind is the most efficient






9. Bacteria ferments biomass with sugars






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






11. Replenish themselves or are continuously present






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






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






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






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






16. Compacting biomass through high temperatures - VED goes up






17. Volumetric energy density






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






19. Burning rubbish/garbage






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






21. Solar energy heats water which turns a turbine






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






23. Difference between high and low tide






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






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






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






27. Volcanoes - hot springs - geysers






28. Solar cells to convert solar energy directly to electricity






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






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. Burning wood






32. Pockets of hot water/steam underground






33. Burning to get heat and electricity






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






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






36. Crops and crop residue






37. Hydrogen sulfide pollution - sources are often national treasures






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






39. 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






40. Semi-permeable dams






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






42. Burning biomass






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






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






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






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






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






48. Hard coal - highest rank - 96% carbon






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






50. Solid biomass to liquid biomass with chemicals and heat
