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. Volumetric energy density






2. Burning to get heat and electricity






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






4. Burning wood






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






6. Crops and crop residue






7. Accumulation of organic material by living things






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






9. Volcanoes - hot springs - geysers






10. Hard coal - highest rank - 96% carbon






11. Burning biomass






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






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






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






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






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






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






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






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






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






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






22. Off shore wind is the most efficient






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






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






25. Bacteria ferments biomass with sugars






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






27. 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






28. Hydrogen sulfide pollution - sources are often national treasures






29. 3 factors that affect volatility






30. Difference between high and low tide






31. Semi-permeable dams






32. Water conservation - jobs - energy -






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






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






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






36. Compacting biomass through high temperatures - VED goes up






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






38. Solid biomass to liquid biomass with chemicals and heat






39. 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






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






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






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






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






44. Solar energy heats water which turns a turbine






45. Soft coal - reduced water (3%)






46. Replenish themselves or are continuously present






47. Pockets of hot water/steam underground






48. Solar cells to convert solar energy directly to electricity






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






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