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. Off shore wind is the most efficient






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






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






4. Hard coal - highest rank - 96% carbon






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






6. Water conservation - jobs - energy -






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






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






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






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






11. Volcanoes - hot springs - geysers






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






13. Burning wood






14. Replenish themselves or are continuously present






15. Solar cells to convert solar energy directly to electricity






16. 3 factors that affect volatility






17. Burning rubbish/garbage






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






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






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






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






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






24. Solar energy heats water which turns a turbine






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






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






27. Burning to get heat and electricity






28. Accumulation of organic material by living things






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






30. Difference between high and low tide






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






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






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






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






35. Pockets of hot water/steam underground






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






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






38. Crops and crop residue






39. Solid biomass to liquid biomass with chemicals and heat






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






41. 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






42. Hydrogen sulfide pollution - sources are often national treasures






43. Soft coal - reduced water (3%)






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






45. Burning biomass






46. Bacteria ferments biomass with sugars






47. Semi-permeable dams






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






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






50. Volumetric energy density
