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. Accumulation of organic material by living things






2. Pockets of hot water/steam underground






3. Semi-permeable dams






4. Burning to get heat and electricity






5. Burning rubbish/garbage






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






7. Solid biomass to liquid biomass with chemicals and heat






8. Hard coal - highest rank - 96% carbon






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






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






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






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






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






14. Compacting biomass through high temperatures - VED goes up






15. Off shore wind is the most efficient






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






17. Burning wood






18. Hydrogen sulfide pollution - sources are often national treasures






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






20. Crops and crop residue






21. Burning biomass






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






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






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






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






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






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






28. Volcanoes - hot springs - geysers






29. Water conservation - jobs - energy -






30. Solar cells to convert solar energy directly to electricity






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






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






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






34. 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






35. 3 factors that affect volatility






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






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






38. Volumetric energy density






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






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






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






42. Replenish themselves or are continuously present






43. Soft coal - reduced water (3%)






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






45. 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






46. Solar energy heats water which turns a turbine






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






48. Bacteria ferments biomass with sugars






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






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