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. Bacteria break down with without oxygen - product is LFGs






2. Pockets of hot water/steam underground






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






4. Volcanoes - hot springs - geysers






5. Crops and crop residue






6. Burning wood






7. Hydrogen sulfide pollution - sources are often national treasures






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






9. 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






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






11. Burning to get heat and electricity






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






13. Solid biomass to liquid biomass with chemicals and heat






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






15. Solar cells to convert solar energy directly to electricity






16. Off shore wind is the most efficient






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






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






19. Burning biomass






20. Replenish themselves or are continuously present






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






22. 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






23. Bacteria ferments biomass with sugars






24. Burning rubbish/garbage






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






26. Volumetric energy density






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






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






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






30. Solar energy heats water which turns a turbine






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






32. Difference between high and low tide






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






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






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






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






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






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






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






40. Compacting biomass through high temperatures - VED goes up






41. Water conservation - jobs - energy -






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






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






44. 3 factors that affect volatility






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






46. Soft coal - reduced water (3%)






47. Accumulation of organic material by living things






48. Semi-permeable dams






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






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