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






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






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






4. Semi-permeable dams






5. Burning wood






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






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






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






9. Soft coal - reduced water (3%)






10. Difference between high and low tide






11. Bacteria ferments biomass with sugars






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






13. Hard coal - highest rank - 96% carbon






14. Solid biomass to liquid biomass with chemicals and heat






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






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






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






18. Pockets of hot water/steam underground






19. Solar energy heats water which turns a turbine






20. Crops and crop residue






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






22. Accumulation of organic material by living things






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






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






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






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






27. Burning biomass






28. Water conservation - jobs - energy -






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






30. Volcanoes - hot springs - geysers






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






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






33. Volumetric energy density






34. Off shore wind is the most efficient






35. 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






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






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






38. Solar cells to convert solar energy directly to electricity






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






40. Burning rubbish/garbage






41. Burning to get heat and electricity






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






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






44. Compacting biomass through high temperatures - VED goes up






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






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






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






48. 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






49. Hydrogen sulfide pollution - sources are often national treasures






50. Replenish themselves or are continuously present
