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. Compacting biomass through high temperatures - VED goes up






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






3. 3 factors that affect volatility






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






5. Crops and crop residue






6. 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






7. Semi-permeable dams






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






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






10. Burning wood






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






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






13. Solar energy heats water which turns a turbine






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






15. Hard coal - highest rank - 96% carbon






16. Solar cells to convert solar energy directly to electricity






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






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






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






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






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






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






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






24. Replenish themselves or are continuously present






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






26. Burning biomass






27. Burning rubbish/garbage






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






29. Soft coal - reduced water (3%)






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






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






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






33. Difference between high and low tide






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






35. Accumulation of organic material by living things






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






37. Burning to get heat and electricity






38. Solid biomass to liquid biomass with chemicals and heat






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






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






41. Hydrogen sulfide pollution - sources are often national treasures






42. Pockets of hot water/steam underground






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






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






45. Water conservation - jobs - energy -






46. Off shore wind is the most efficient






47. Bacteria ferments biomass with sugars






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






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






50. Volumetric energy density
