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






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






3. Solid biomass to liquid biomass with chemicals and heat






4. Compacting biomass through high temperatures - VED goes up






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






6. Burning to get heat and electricity






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






8. Hydrogen sulfide pollution - sources are often national treasures






9. Off shore wind is the most efficient






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






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






12. Bacteria ferments biomass with sugars






13. 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






14. Semi-permeable dams






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






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






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






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






19. 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






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






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






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






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






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






25. Soft coal - reduced water (3%)






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






27. Burning wood






28. Solar energy heats water which turns a turbine






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






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






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






32. Difference between high and low tide






33. Burning rubbish/garbage






34. Water conservation - jobs - energy -






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






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






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






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






39. Hard coal - highest rank - 96% carbon






40. Volcanoes - hot springs - geysers






41. Replenish themselves or are continuously present






42. 3 factors that affect volatility






43. Solar cells to convert solar energy directly to electricity






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






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






46. Burning biomass






47. Pockets of hot water/steam underground






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






49. Accumulation of organic material by living things






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