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. 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






3. Water conservation - jobs - energy -






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






5. Bacteria ferments biomass with sugars






6. Off shore wind is the most efficient






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






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






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






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






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






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






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






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






15. Accumulation of organic material by living things






16. Compacting biomass through high temperatures - VED goes up






17. 3 factors that affect volatility






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






19. Solar energy heats water which turns a turbine






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






21. Semi-permeable dams






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






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






24. Replenish themselves or are continuously present






25. Pockets of hot water/steam underground






26. Volcanoes - hot springs - geysers






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






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






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






30. Crops and crop residue






31. Soft coal - reduced water (3%)






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






33. 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






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






35. Difference between high and low tide






36. Solid biomass to liquid biomass with chemicals and heat






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






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






39. Hard coal - highest rank - 96% carbon






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






41. Burning wood






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






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






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






45. Burning rubbish/garbage






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






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






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






49. Burning to get heat and electricity






50. Solar cells to convert solar energy directly to electricity
