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. Difference between high and low tide






2. Replenish themselves or are continuously present






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






4. Compacting biomass through high temperatures - VED goes up






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






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






7. Burning rubbish/garbage






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






9. Solar energy heats water which turns a turbine






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






11. Volumetric energy density






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






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






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






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






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






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






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






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






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






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






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






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






24. Crops and crop residue






25. Accumulation of organic material by living things






26. Burning to get heat and electricity






27. Solar cells to convert solar energy directly to electricity






28. Volcanoes - hot springs - geysers






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






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






31. 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






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






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






34. Burning wood






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






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






37. 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






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






39. Semi-permeable dams






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






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






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






43. Hard coal - highest rank - 96% carbon






44. Soft coal - reduced water (3%)






45. Burning biomass






46. Pockets of hot water/steam underground






47. Off shore wind is the most efficient






48. 3 factors that affect volatility






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






50. Water conservation - jobs - energy -
