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






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






3. Solid biomass to liquid biomass with chemicals and heat






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






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






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






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






8. Water conservation - jobs - energy -






9. Hydrogen sulfide pollution - sources are often national treasures






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






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






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






13. Accumulation of organic material by living things






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






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






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






17. 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






18. 3 factors that affect volatility






19. Volcanoes - hot springs - geysers






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






21. Burning to get heat and electricity






22. Replenish themselves or are continuously present






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






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






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






26. Solar cells to convert solar energy directly to electricity






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






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






29. Solar energy heats water which turns a turbine






30. Soft coal - reduced water (3%)






31. Off shore wind is the most efficient






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






33. Compacting biomass through high temperatures - VED goes up






34. Crops and crop residue






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






36. Hard coal - highest rank - 96% carbon






37. 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






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






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






40. Volumetric energy density






41. Burning rubbish/garbage






42. Burning biomass






43. Semi-permeable dams






44. Difference between high and low tide






45. Bacteria ferments biomass with sugars






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






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






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






49. Burning wood






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