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






2. Difference between high and low tide






3. Soft coal - reduced water (3%)






4. Solar energy heats water which turns a turbine






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






6. Solid biomass to liquid biomass with chemicals and heat






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






8. Semi-permeable dams






9. Volcanoes - hot springs - geysers






10. 3 factors that affect volatility






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






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






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






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






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






16. Volumetric energy density






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






18. Off shore wind is the most efficient






19. Pockets of hot water/steam underground






20. Burning wood






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






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






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






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






25. Crops and crop residue






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






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






28. Replenish themselves or are continuously present






29. 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






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






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






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






33. Water conservation - jobs - energy -






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. Hydrogen sulfide pollution - sources are often national treasures






36. Accumulation of organic material by living things






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






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






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






40. Compacting biomass through high temperatures - VED goes up






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






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






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






44. Burning rubbish/garbage






45. Hard coal - highest rank - 96% carbon






46. Bacteria ferments biomass with sugars






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






48. Burning biomass






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






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