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. 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






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






3. Solar energy heats water which turns a turbine






4. Difference between high and low tide






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






6. Bacteria ferments biomass with sugars






7. Pockets of hot water/steam underground






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






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






10. Water conservation - jobs - energy -






11. 3 factors that affect volatility






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






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






14. Accumulation of organic material by living things






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






16. Soft coal - reduced water (3%)






17. Hydrogen sulfide pollution - sources are often national treasures






18. Volcanoes - hot springs - geysers






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






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






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






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






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






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






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






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






27. Hard coal - highest rank - 96% carbon






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






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






30. Replenish themselves or are continuously present






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






32. Off shore wind is the most efficient






33. Solar cells to convert solar energy directly to electricity






34. 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






35. Burning biomass






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






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






38. Compacting biomass through high temperatures - VED goes up






39. Volumetric energy density






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






41. Burning rubbish/garbage






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






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






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






45. Solid biomass to liquid biomass with chemicals and heat






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






47. Semi-permeable dams






48. Burning wood






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






50. Burning to get heat and electricity
