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






2. Burning to get heat and electricity






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






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






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






6. Burning wood






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






8. Difference between high and low tide






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






10. Solar cells to convert solar energy directly to electricity






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






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






13. Hard coal - highest rank - 96% carbon






14. Bacteria ferments biomass with sugars






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






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






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






18. 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






19. Semi-permeable dams






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






21. Accumulation of organic material by living things






22. Water conservation - jobs - energy -






23. Hydrogen sulfide pollution - sources are often national treasures






24. Burning biomass






25. Crops and crop residue






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






27. Off shore wind is the most efficient






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






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






30. 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






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






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






33. Burning rubbish/garbage






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






35. Solid biomass to liquid biomass with chemicals and heat






36. Volumetric energy density






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






38. Volcanoes - hot springs - geysers






39. Compacting biomass through high temperatures - VED goes up






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






41. Replenish themselves or are continuously present






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






43. Pockets of hot water/steam underground






44. Soft coal - reduced water (3%)






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






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






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






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






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






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