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. Solar energy heats water which turns a turbine






2. Volcanoes - hot springs - geysers






3. 3 factors that affect volatility






4. Off shore wind is the most efficient






5. Hard coal - highest rank - 96% carbon






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






7. Burning wood






8. Hydrogen sulfide pollution - sources are often national treasures






9. Crops and crop residue






10. Water conservation - jobs - energy -






11. Bacteria ferments biomass with sugars






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






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






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






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






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






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. Compacting biomass through high temperatures - VED goes up






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






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






21. Burning to get heat and electricity






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






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






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






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






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






27. Pockets of hot water/steam underground






28. Replenish themselves or are continuously present






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






30. Difference between high and low tide






31. Solid biomass to liquid biomass with chemicals and heat






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






33. 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






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






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






36. Volumetric energy density






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






38. Accumulation of organic material by living things






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






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






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






42. Solar cells to convert solar energy directly to electricity






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






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






45. Burning rubbish/garbage






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






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






48. Semi-permeable dams






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






50. Soft coal - reduced water (3%)
