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






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






3. Water conservation - jobs - energy -






4. Burning rubbish/garbage






5. 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






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






7. Burning biomass






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






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






10. Pockets of hot water/steam underground






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






12. Soft coal - reduced water (3%)






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






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






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






16. Accumulation of organic material by living things






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






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






19. Crops and crop residue






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






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






22. Bacteria ferments biomass with sugars






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






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






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






26. 3 factors that affect volatility






27. Hard coal - highest rank - 96% carbon






28. Difference between high and low tide






29. Solar energy heats water which turns a turbine






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






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






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






33. Off shore wind is the most efficient






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






35. Burning wood






36. Burning to get heat and electricity






37. Solar cells to convert solar energy directly to electricity






38. Volcanoes - hot springs - geysers






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






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






41. Volumetric energy density






42. Semi-permeable dams






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






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






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






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






47. Solid biomass to liquid biomass with chemicals and heat






48. Compacting biomass through high temperatures - VED goes up






49. Replenish themselves or are continuously present






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