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. Burning to get heat and electricity






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






3. Burning wood






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






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






6. Difference between high and low tide






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






8. Solar cells to convert solar energy directly to electricity






9. 3 factors that affect volatility






10. 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






11. Water conservation - jobs - energy -






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






13. Pockets of hot water/steam underground






14. Burning biomass






15. Compacting biomass through high temperatures - VED goes up






16. Solid biomass to liquid biomass with chemicals and heat






17. Crops and crop residue






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






19. Off shore wind is the most efficient






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






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






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






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






24. Volumetric energy density






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






26. Hydrogen sulfide pollution - sources are often national treasures






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






28. Bacteria ferments biomass with sugars






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






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






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






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






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






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






35. Hard coal - highest rank - 96% carbon






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






37. Burning rubbish/garbage






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






39. Solar energy heats water which turns a turbine






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






41. Soft coal - reduced water (3%)






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






43. 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






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






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






46. Accumulation of organic material by living things






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






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






49. Replenish themselves or are continuously present






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