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






2. Replenish themselves or are continuously present






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






4. Water conservation - jobs - energy -






5. Volcanoes - hot springs - geysers






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






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






8. 3 factors that affect volatility






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






10. Bacteria ferments biomass with sugars






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






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






13. Accumulation of organic material by living things






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






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






16. Off shore wind is the most efficient






17. 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






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






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






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






21. 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






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






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






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






25. Solid biomass to liquid biomass with chemicals and heat






26. Hydrogen sulfide pollution - sources are often national treasures






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






28. Burning wood






29. Difference between high and low tide






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






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






32. Soft coal - reduced water (3%)






33. Burning biomass






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






35. Solar energy heats water which turns a turbine






36. Solar cells to convert solar energy directly to electricity






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






38. Burning to get heat and electricity






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. Volumetric energy density






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






44. Semi-permeable dams






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






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






47. Hard coal - highest rank - 96% carbon






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






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






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