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






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






3. 3 factors that affect volatility






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. Bacteria break down with without oxygen - product is LFGs






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






7. 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






8. Hydrogen sulfide pollution - sources are often national treasures






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






10. Volcanoes - hot springs - geysers






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






12. Solid biomass to liquid biomass with chemicals and heat






13. Pockets of hot water/steam underground






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






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






16. Bacteria ferments biomass with sugars






17. Volumetric energy density






18. Burning rubbish/garbage






19. Burning biomass






20. Soft coal - reduced water (3%)






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






22. Difference between high and low tide






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






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






25. Replenish themselves or are continuously present






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






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






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






29. Crops and crop residue






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






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






32. Water conservation - jobs - energy -






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






34. Burning wood






35. Hard coal - highest rank - 96% carbon






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






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






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






39. Compacting biomass through high temperatures - VED goes up






40. Solar cells to convert solar energy directly to electricity






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






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






43. Semi-permeable dams






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






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






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






47. 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






48. Burning to get heat and electricity






49. Off shore wind is the most efficient






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