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. Organic materials are changed to lighter - more volatile hydrocarbons






2. Burning rubbish/garbage






3. Replenish themselves or are continuously present






4. 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






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






6. Hard coal - highest rank - 96% carbon






7. Burning to get heat and electricity






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






9. Pockets of hot water/steam underground






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






11. Burning biomass






12. Water conservation - jobs - energy -






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






14. Off shore wind is the most efficient






15. Hydrogen sulfide pollution - sources are often national treasures






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






17. Volcanoes - hot springs - geysers






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






19. Bacteria ferments biomass with sugars






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






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






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






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






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






25. Soft coal - reduced water (3%)






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






27. Difference between high and low tide






28. Solar energy heats water which turns a turbine






29. Solar cells to convert solar energy directly to electricity






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






31. Semi-permeable dams






32. 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






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






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






35. Burning wood






36. Accumulation of organic material by living things






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






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






39. Crops and crop residue






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






41. Compacting biomass through high temperatures - VED goes up






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






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






44. 3 factors that affect volatility






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






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






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






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






49. Volumetric energy density






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