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. 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






2. 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






3. Soft coal - reduced water (3%)






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






5. Burning to get heat and electricity






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






7. 3 factors that affect volatility






8. Solid biomass to liquid biomass with chemicals and heat






9. Hard coal - highest rank - 96% carbon






10. Off shore wind is the most efficient






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






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






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






14. Solar cells to convert solar energy directly to electricity






15. Difference between high and low tide






16. Volumetric energy density






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






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






19. Burning biomass






20. Compacting biomass through high temperatures - VED goes up






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






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






23. Accumulation of organic material by living things






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






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






26. Bacteria ferments biomass with sugars






27. Hydrogen sulfide pollution - sources are often national treasures






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






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






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






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






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






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






34. Solar energy heats water which turns a turbine






35. Burning rubbish/garbage






36. Pockets of hot water/steam underground






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






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






39. Volcanoes - hot springs - geysers






40. Semi-permeable dams






41. Replenish themselves or are continuously present






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






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






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






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






46. Burning wood






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






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






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






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