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. Compacting biomass through high temperatures - VED goes up






2. Burning wood






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






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






5. Semi-permeable dams






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






7. Pockets of hot water/steam underground






8. Off shore wind is the most efficient






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






10. Accumulation of organic material by living things






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






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






13. Burning biomass






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






15. Hydrogen sulfide pollution - sources are often national treasures






16. Burning rubbish/garbage






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






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






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






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






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






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






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






24. Solar cells to convert solar energy directly to electricity






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






26. Volcanoes - hot springs - geysers






27. Replenish themselves or are continuously present






28. Solar energy heats water which turns a turbine






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






30. Bacteria ferments biomass with sugars






31. Water conservation - jobs - energy -






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






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






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






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






36. 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






37. Volumetric energy density






38. Difference between high and low tide






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






40. Soft coal - reduced water (3%)






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






42. Solid biomass to liquid biomass with chemicals and heat






43. Burning to get heat and electricity






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






45. Crops and crop residue






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






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






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






49. 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






50. 3 factors that affect volatility
