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






2. Hard coal - highest rank - 96% carbon






3. Soft coal - reduced water (3%)






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






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. Crops and crop residue






7. Bacteria ferments biomass with sugars






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






9. Volcanoes - hot springs - geysers






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






11. Difference between high and low tide






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






13. Semi-permeable dams






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






15. Solid biomass to liquid biomass with chemicals and heat






16. Accumulation of organic material by living things






17. Solar energy heats water which turns a turbine






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






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






20. Replenish themselves or are continuously present






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






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






23. Burning biomass






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






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






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






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






28. Compacting biomass through high temperatures - VED goes up






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






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






31. Solar cells to convert solar energy directly to electricity






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






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






34. Hydrogen sulfide pollution - sources are often national treasures






35. Burning wood






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






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






38. 3 factors that affect volatility






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






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






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






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






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






44. Off shore wind is the most efficient






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






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






47. Volumetric energy density






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






49. Water conservation - jobs - energy -






50. Burning to get heat and electricity
