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






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






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






4. Burning biomass






5. Hard coal - highest rank - 96% carbon






6. Solar cells to convert solar energy directly to electricity






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






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






9. Replenish themselves or are continuously present






10. Volumetric energy density






11. Difference between high and low tide






12. Volcanoes - hot springs - geysers






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






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






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






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






17. 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






18. Solar energy heats water which turns a turbine






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






20. Bacteria ferments biomass with sugars






21. Solid biomass to liquid biomass with chemicals and heat






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






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






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






25. Off shore wind is the most efficient






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






27. Accumulation of organic material by living things






28. Burning wood






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






30. 3 factors that affect volatility






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






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






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






34. 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






35. Crops and crop residue






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






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






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






39. Burning rubbish/garbage






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






41. Hydrogen sulfide pollution - sources are often national treasures






42. Soft coal - reduced water (3%)






43. Semi-permeable dams






44. Pockets of hot water/steam underground






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






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






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






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






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






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