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 -No direct pollution though! Bird death ray - Startup cost






2. 3 factors that affect volatility






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






4. Solid biomass to liquid biomass with chemicals and heat






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






6. Semi-permeable dams






7. Accumulation of organic material by living things






8. Volcanoes - hot springs - geysers






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






10. Pockets of hot water/steam underground






11. Replenish themselves or are continuously present






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






13. Off shore wind is the most efficient






14. Burning biomass






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






16. Solar cells to convert solar energy directly to electricity






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






18. Hydrogen sulfide pollution - sources are often national treasures






19. Water conservation - jobs - energy -






20. Burning rubbish/garbage






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






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






23. Compacting biomass through high temperatures - VED goes up






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






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






26. Difference between high and low tide






27. Volumetric energy density






28. Bacteria ferments biomass with sugars






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






30. Burning wood






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






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






33. Hard coal - highest rank - 96% carbon






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






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






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






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






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






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






40. 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






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






42. Burning to get heat and electricity






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






44. Solar energy heats water which turns a turbine






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






46. Soft coal - reduced water (3%)






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






48. Crops and crop residue






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






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