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. Bacteria ferments biomass with sugars






2. Burning rubbish/garbage






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






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






5. Replenish themselves or are continuously present






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






7. Solar energy heats water which turns a turbine






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






9. Hydrogen sulfide pollution - sources are often national treasures






10. 3 factors that affect volatility






11. Solid biomass to liquid biomass with chemicals and heat






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






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






14. Crops and crop residue






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






16. Water conservation - jobs - energy -






17. Soft coal - reduced water (3%)






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






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






20. Hard coal - highest rank - 96% carbon






21. Pockets of hot water/steam underground






22. Semi-permeable dams






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






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






25. Off shore wind is the most efficient






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






27. Burning wood






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






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






30. Difference between high and low tide






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






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






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






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






35. Accumulation of organic material by living things






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






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






38. Burning to get heat and electricity






39. 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






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






41. Solar cells to convert solar energy directly to electricity






42. Volcanoes - hot springs - geysers






43. Compacting biomass through high temperatures - VED goes up






44. 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






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






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






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






48. Burning biomass






49. Volumetric energy density






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