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






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






4. Solar energy heats water which turns a turbine






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






6. Off shore wind is the most efficient






7. Burning wood






8. Semi-permeable dams






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






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






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






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






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






14. Soft coal - reduced water (3%)






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






16. 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






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






18. Burning to get heat and electricity






19. Solar cells to convert solar energy directly to electricity






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






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






22. Hard coal - highest rank - 96% carbon






23. Volumetric energy density






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






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






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






27. 3 factors that affect volatility






28. Difference between high and low tide






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






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






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






32. Accumulation of organic material by living things






33. Volcanoes - hot springs - geysers






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






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






36. Water conservation - jobs - energy -






37. Replenish themselves or are continuously present






38. Crops and crop residue






39. Hydrogen sulfide pollution - sources are often national treasures






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






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






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






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






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






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






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






47. Solid biomass to liquid biomass with chemicals and heat






48. Bacteria ferments biomass with sugars






49. Burning biomass






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