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






2. Solar cells to convert solar energy directly to electricity






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






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






5. Solid biomass to liquid biomass with chemicals and heat






6. Burning biomass






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






8. Solar energy heats water which turns a turbine






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






10. Semi-permeable dams






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






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






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






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






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






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






17. Accumulation of organic material by living things






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






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






20. Off shore wind is the most efficient






21. Volcanoes - hot springs - geysers






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






23. Hydrogen sulfide pollution - sources are often national treasures






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






25. Volumetric energy density






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






27. Burning rubbish/garbage






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






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






30. Burning to get heat and electricity






31. Difference between high and low tide






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






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






34. 3 factors that affect volatility






35. Water conservation - jobs - energy -






36. Burning wood






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






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






39. Compacting biomass through high temperatures - VED goes up






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






41. 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






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






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






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






45. Replenish themselves or are continuously present






46. Hard coal - highest rank - 96% carbon






47. Crops and crop residue






48. Soft coal - reduced water (3%)






49. Bacteria ferments biomass with sugars






50. Pockets of hot water/steam underground
