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






2. Volcanoes - hot springs - geysers






3. Soft coal - reduced water (3%)






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






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






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






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






8. Semi-permeable dams






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






10. Hard coal - highest rank - 96% carbon






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






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






13. Off shore wind is the most efficient






14. Burning wood






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






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






17. 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






18. Replenish themselves or are continuously present






19. Solar energy heats water which turns a turbine






20. Pockets of hot water/steam underground






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






22. Burning rubbish/garbage






23. Solid biomass to liquid biomass with chemicals and heat






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






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






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






27. Water conservation - jobs - energy -






28. Burning biomass






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






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






31. Burning to get heat and electricity






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






33. Difference between high and low tide






34. Volumetric energy density






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






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






37. 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






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






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






40. 3 factors that affect volatility






41. Hydrogen sulfide pollution - sources are often national treasures






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






43. Compacting biomass through high temperatures - VED goes up






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






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






46. Bacteria ferments biomass with sugars






47. Accumulation of organic material by living things






48. Solar cells to convert solar energy directly to electricity






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






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