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






3. Off shore wind is the most efficient






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






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






6. Solid biomass to liquid biomass with chemicals and heat






7. Solar energy heats water which turns a turbine






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






9. Replenish themselves or are continuously present






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






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






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






13. Burning biomass






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






15. Semi-permeable dams






16. Difference between high and low tide






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






18. 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






19. Burning to get heat and electricity






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






21. Hydrogen sulfide pollution - sources are often national treasures






22. Crops and crop residue






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






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






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






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






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






28. Volcanoes - hot springs - geysers






29. Accumulation of organic material by living things






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






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






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






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






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






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






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






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






38. Pockets of hot water/steam underground






39. Hard coal - highest rank - 96% carbon






40. Solar cells to convert solar energy directly to electricity






41. 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






42. 3 factors that affect volatility






43. Soft coal - reduced water (3%)






44. Water conservation - jobs - energy -






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






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






47. Bacteria ferments biomass with sugars






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






49. Burning wood






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