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. Bacteria ferments biomass with sugars






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






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






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






5. Semi-permeable dams






6. Volcanoes - hot springs - geysers






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






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






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






10. Burning rubbish/garbage






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






12. Off shore wind is the most efficient






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






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






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






16. Burning to get heat and electricity






17. Solid biomass to liquid biomass with chemicals and heat






18. Accumulation of organic material by living things






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






20. Crops and crop residue






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






22. Hydrogen sulfide pollution - sources are often national treasures






23. Replenish themselves or are continuously present






24. Compacting biomass through high temperatures - VED goes up






25. Pockets of hot water/steam underground






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






27. 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






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






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






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






31. 3 factors that affect volatility






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






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






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






35. Soft coal - reduced water (3%)






36. Hard coal - highest rank - 96% carbon






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






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






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






40. Water conservation - jobs - energy -






41. Burning biomass






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






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






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






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






46. Volumetric energy density






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






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






49. Burning wood






50. 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
