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. Semi-permeable dams






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






3. Pockets of hot water/steam underground






4. Crops and crop residue






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






6. Burning wood






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






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






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






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






11. Solid biomass to liquid biomass with chemicals and heat






12. Burning rubbish/garbage






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






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






15. Accumulation of organic material by living things






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






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






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






19. Replenish themselves or are continuously present






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






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






22. Hydrogen sulfide pollution - sources are often national treasures






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






24. Hard coal - highest rank - 96% carbon






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






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






27. Solar energy heats water which turns a turbine






28. Soft coal - reduced water (3%)






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






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






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






32. Burning biomass






33. Burning to get heat and electricity






34. Difference between high and low tide






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






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






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






39. Volcanoes - hot springs - geysers






40. Off shore wind is the most efficient






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






42. Solar cells to convert solar energy directly to electricity






43. Bacteria ferments biomass with sugars






44. Volumetric energy density






45. Compacting biomass through high temperatures - VED goes up






46. Water conservation - jobs - energy -






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






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






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






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