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. Solid biomass to liquid biomass with chemicals and heat






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






3. Accumulation of organic material by living things






4. 3 factors that affect volatility






5. Bacteria ferments biomass with sugars






6. Soft coal - reduced water (3%)






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






8. Volumetric energy density






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






10. Burning wood






11. Solar cells to convert solar energy directly to electricity






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






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






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






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






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






17. Hydrogen sulfide pollution - sources are often national treasures






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






19. Solar energy heats water which turns a turbine






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






21. Volcanoes - hot springs - geysers






22. 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






23. Off shore wind is the most efficient






24. Replenish themselves or are continuously present






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






26. Water conservation - jobs - energy -






27. Burning rubbish/garbage






28. Compacting biomass through high temperatures - VED goes up






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






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






31. Hard coal - highest rank - 96% carbon






32. Burning to get heat and electricity






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






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






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






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






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






38. Burning biomass






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






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






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






42. Crops and crop residue






43. Difference between high and low tide






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






45. Pockets of hot water/steam underground






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






47. Semi-permeable dams






48. 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






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






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