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






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






3. Solar energy heats water which turns a turbine






4. 3 factors that affect volatility






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






6. Burning rubbish/garbage






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






8. Bacteria ferments biomass with sugars






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






10. Crops and crop residue






11. Solid biomass to liquid biomass with chemicals and heat






12. Accumulation of organic material by living things






13. Hard coal - highest rank - 96% carbon






14. Hydrogen sulfide pollution - sources are often national treasures






15. Burning biomass






16. Solar cells to convert solar energy directly to electricity






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






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






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






20. 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






21. Burning wood






22. 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






23. Off shore wind is the most efficient






24. Compacting biomass through high temperatures - VED goes up






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






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






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






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






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






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






31. Burning to get heat and electricity






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






33. Soft coal - reduced water (3%)






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






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






36. Semi-permeable dams






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






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






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






40. Difference between high and low tide






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






42. Water conservation - jobs - energy -






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






44. Volcanoes - hot springs - geysers






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






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






47. Volumetric energy density






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






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






50. Pockets of hot water/steam underground
