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






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






3. Hard coal - highest rank - 96% carbon






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






5. 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






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






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






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






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






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






11. Bacteria ferments biomass with sugars






12. Replenish themselves or are continuously present






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






14. Water conservation - jobs - energy -






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






16. Hydrogen sulfide pollution - sources are often national treasures






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






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






19. Burning to get heat and electricity






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. Burning rubbish/garbage






22. Burning biomass






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






24. Off shore wind is the most efficient






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






26. Solar cells to convert solar energy directly to electricity






27. 3 factors that affect volatility






28. Compacting biomass through high temperatures - VED goes up






29. Volcanoes - hot springs - geysers






30. Soft coal - reduced water (3%)






31. Solid biomass to liquid biomass with chemicals and heat






32. Burning wood






33. Volumetric energy density






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






35. Semi-permeable dams






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






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






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






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






40. Accumulation of organic material by living things






41. Difference between high and low tide






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






43. Pockets of hot water/steam underground






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






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






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






47. Solar energy heats water which turns a turbine






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






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






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