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. Burning rubbish/garbage






2. Volumetric energy density






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






4. Difference between high and low tide






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. Pockets of hot water/steam underground






7. Off shore wind is the most efficient






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






9. Burning wood






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






11. Compacting biomass through high temperatures - VED goes up






12. Accumulation of organic material by living things






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






14. Replenish themselves or are continuously present






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






16. Solid biomass to liquid biomass with chemicals and heat






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






18. Solar energy heats water which turns a turbine






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






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






21. 3 factors that affect volatility






22. Water conservation - jobs - energy -






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






24. Soft coal - reduced water (3%)






25. Hydrogen sulfide pollution - sources are often national treasures






26. Crops and crop residue






27. Burning biomass






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






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






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






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






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






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






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






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






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






37. Solar cells to convert solar energy directly to electricity






38. Burning to get heat and electricity






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






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






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






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






43. Semi-permeable dams






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






45. Bacteria ferments biomass with sugars






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






47. Hard coal - highest rank - 96% carbon






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






49. Volcanoes - hot springs - geysers






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