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






2. 3 factors that affect volatility






3. Volumetric energy density






4. Bacteria ferments biomass with sugars






5. Semi-permeable dams






6. Hydrogen sulfide pollution - sources are often national treasures






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






8. 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






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






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






11. Hard coal - highest rank - 96% carbon






12. Pockets of hot water/steam underground






13. 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






14. Off shore wind is the most efficient






15. Burning wood






16. Burning rubbish/garbage






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






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






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






20. Burning biomass






21. Replenish themselves or are continuously present






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






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






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






25. Volcanoes - hot springs - geysers






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






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






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






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






30. Burning to get heat and electricity






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






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






33. Solid biomass to liquid biomass with chemicals and heat






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






35. Solar energy heats water which turns a turbine






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






37. Soft coal - reduced water (3%)






38. Water conservation - jobs - energy -






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






40. Compacting biomass through high temperatures - VED goes up






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






42. Accumulation of organic material by living things






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






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






45. Difference between high and low tide






46. Crops and crop residue






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






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






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






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