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. Organic materials are changed to lighter - more volatile hydrocarbons






2. Burning biomass






3. 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






4. Hard coal - highest rank - 96% carbon






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






6. Solid biomass to liquid biomass with chemicals and heat






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






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






9. Crops and crop residue






10. Burning rubbish/garbage






11. 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






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






13. Semi-permeable dams






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






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






16. Replenish themselves or are continuously present






17. Off shore wind is the most efficient






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






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






20. Pockets of hot water/steam underground






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






22. Volcanoes - hot springs - geysers






23. Soft coal - reduced water (3%)






24. Burning to get heat and electricity






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






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






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






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






29. Volumetric energy density






30. Bacteria ferments biomass with sugars






31. Compacting biomass through high temperatures - VED goes up






32. Difference between high and low tide






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






34. Solar cells to convert solar energy directly to electricity






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






36. Water conservation - jobs - energy -






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






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






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






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






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






42. 3 factors that affect volatility






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






44. Burning wood






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






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






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






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






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. Hydrogen sulfide pollution - sources are often national treasures
