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






2. Replenish themselves or are continuously present






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






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






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






6. Solar energy heats water which turns a turbine






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






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






9. Solid biomass to liquid biomass with chemicals and heat






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






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






12. Difference between high and low tide






13. Hydrogen sulfide pollution - sources are often national treasures






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






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






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






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






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






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






20. 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






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






22. Bacteria ferments biomass with sugars






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






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






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






26. Crops and crop residue






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






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






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






30. Semi-permeable dams






31. 3 factors that affect volatility






32. Water conservation - jobs - energy -






33. Hard coal - highest rank - 96% carbon






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






35. Burning wood






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






37. 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






38. Volumetric energy density






39. Off shore wind is the most efficient






40. Volcanoes - hot springs - geysers






41. Accumulation of organic material by living things






42. Pockets of hot water/steam underground






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






44. Burning biomass






45. Compacting biomass through high temperatures - VED goes up






46. Soft coal - reduced water (3%)






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






48. Solar cells to convert solar energy directly to electricity






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






50. Burning to get heat and electricity
