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






2. Accumulation of organic material by living things






3. Burning biomass






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






5. Replenish themselves or are continuously present






6. Crops and crop residue






7. Soft coal - reduced water (3%)






8. Off shore wind is the most efficient






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






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






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






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






13. Compacting biomass through high temperatures - VED goes up






14. Volcanoes - hot springs - geysers






15. Hydrogen sulfide pollution - sources are often national treasures






16. 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






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






18. Solar cells to convert solar energy directly to electricity






19. Pockets of hot water/steam underground






20. 3 factors that affect volatility






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






22. Difference between high and low tide






23. 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






24. Burning rubbish/garbage






25. Solid biomass to liquid biomass with chemicals and heat






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






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






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






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






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






31. Semi-permeable dams






32. Volumetric energy density






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






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






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






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






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






38. Solar energy heats water which turns a turbine






39. Burning wood






40. Burning to get heat and electricity






41. Hard coal - highest rank - 96% carbon






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






43. Bacteria ferments biomass with sugars






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






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






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






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






49. Water conservation - jobs - energy -






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