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 -No direct pollution though! Bird death ray - Startup cost






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






3. Replenish themselves or are continuously present






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






5. Crops and crop residue






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






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






8. Burning to get heat and electricity






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






10. Burning wood






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






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






13. 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






14. Volumetric energy density






15. 3 factors that affect volatility






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






17. Off shore wind is the most efficient






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






19. Pockets of hot water/steam underground






20. Soft coal - reduced water (3%)






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






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






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






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






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






26. Water conservation - jobs - energy -






27. Hard coal - highest rank - 96% carbon






28. 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






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






30. Solar cells to convert solar energy directly to electricity






31. Bacteria ferments biomass with sugars






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






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






34. Compacting biomass through high temperatures - VED goes up






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






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






37. Solar energy heats water which turns a turbine






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






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






40. Solid biomass to liquid biomass with chemicals and heat






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






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






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






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






45. Accumulation of organic material by living things






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






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






48. Semi-permeable dams






49. Burning biomass






50. Difference between high and low tide
