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. 3 factors that affect volatility






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






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






4. Off shore wind is the most efficient






5. Difference between high and low tide






6. Burning to get heat and electricity






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






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






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






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






11. Volcanoes - hot springs - geysers






12. Water conservation - jobs - energy -






13. Hard coal - highest rank - 96% carbon






14. Soft coal - reduced water (3%)






15. Bacteria ferments biomass with sugars






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






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






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






19. Burning biomass






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






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






22. 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






23. Solar energy heats water which turns a turbine






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






25. Pockets of hot water/steam underground






26. Accumulation of organic material by living things






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






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






29. 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






30. Burning wood






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






32. Solar cells to convert solar energy directly to electricity






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






34. Crops and crop residue






35. Solid biomass to liquid biomass with chemicals and heat






36. Hydrogen sulfide pollution - sources are often national treasures






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






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






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






40. Semi-permeable dams






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






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






43. Burning rubbish/garbage






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






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






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






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






48. Volumetric energy density






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






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