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. Volcanoes - hot springs - geysers






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






3. 3 factors that affect volatility






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






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






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






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






8. Difference between high and low tide






9. Burning wood






10. Water conservation - jobs - energy -






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






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






13. Hydrogen sulfide pollution - sources are often national treasures






14. Burning rubbish/garbage






15. Burning to get heat and electricity






16. Burning biomass






17. Solar energy heats water which turns a turbine






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






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






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






21. Compacting biomass through high temperatures - VED goes up






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






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






24. Volumetric energy density






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






26. Pockets of hot water/steam underground






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






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






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






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






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






32. Soft coal - reduced water (3%)






33. Solar cells to convert solar energy directly to electricity






34. Replenish themselves or are continuously present






35. Solid biomass to liquid biomass with chemicals and heat






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






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






39. Crops and crop residue






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






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






42. Off shore wind is the most efficient






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






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






45. Semi-permeable dams






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






47. Bacteria ferments biomass with sugars






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






49. Hard coal - highest rank - 96% carbon






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