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. 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






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






3. Compacting biomass through high temperatures - VED goes up






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






5. Crops and crop residue






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






7. 3 factors that affect volatility






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






9. Burning to get heat and electricity






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






11. Hydrogen sulfide pollution - sources are often national treasures






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






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






14. Bacteria ferments biomass with sugars






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






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






17. Replenish themselves or are continuously present






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. Pockets of hot water/steam underground






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






21. Difference between high and low tide






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






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






24. Solar cells to convert solar energy directly to electricity






25. Solar energy heats water which turns a turbine






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






27. Volcanoes - hot springs - geysers






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






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






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






31. Accumulation of organic material by living things






32. Solid biomass to liquid biomass with chemicals and heat






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






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






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






36. Water conservation - jobs - energy -






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






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






39. Off shore wind is the most efficient






40. Hard coal - highest rank - 96% carbon






41. Volumetric energy density






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






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






44. Semi-permeable dams






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






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






47. Burning rubbish/garbage






48. Burning biomass






49. Soft coal - reduced water (3%)






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