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. Crops and crop residue






2. Volumetric energy density






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






4. Burning rubbish/garbage






5. Pockets of hot water/steam underground






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






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






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






9. Bacteria ferments biomass with sugars






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






11. 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






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






13. Replenish themselves or are continuously present






14. Semi-permeable dams






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






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






17. Hydrogen sulfide pollution - sources are often national treasures






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






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






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






21. 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






22. Soft coal - reduced water (3%)






23. Compacting biomass through high temperatures - VED goes up






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






25. Burning wood






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






27. Off shore wind is the most efficient






28. Solar energy heats water which turns a turbine






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






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






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






32. 3 factors that affect volatility






33. Difference between high and low tide






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






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






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






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






38. Solar cells to convert solar energy directly to electricity






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






40. Accumulation of organic material by living things






41. Water conservation - jobs - energy -






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






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






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






45. Burning biomass






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






47. Burning to get heat and electricity






48. Solid biomass to liquid biomass with chemicals and heat






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






50. Volcanoes - hot springs - geysers
