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






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






3. 3 factors that affect volatility






4. Solid biomass to liquid biomass with chemicals and heat






5. Pockets of hot water/steam underground






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






7. Burning to get heat and electricity






8. Solar cells to convert solar energy directly to electricity






9. Semi-permeable dams






10. Burning biomass






11. 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






12. Hydrogen sulfide pollution - sources are often national treasures






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






14. Volcanoes - hot springs - geysers






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






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






17. Accumulation of organic material by living things






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






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






20. 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






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






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






23. Replenish themselves or are continuously present






24. Off shore wind is the most efficient






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






26. Bacteria ferments biomass with sugars






27. Hard coal - highest rank - 96% carbon






28. Difference between high and low tide






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






30. Crops and crop residue






31. Volumetric energy density






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






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






34. Burning wood






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






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






37. Water conservation - jobs - energy -






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






39. Burning rubbish/garbage






40. Soft coal - reduced water (3%)






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






42. Solar energy heats water which turns a turbine






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






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






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






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






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






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






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






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