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






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






3. Hard coal - highest rank - 96% carbon






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






5. 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






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






7. Burning to get heat and electricity






8. Burning wood






9. Solar cells to convert solar energy directly to electricity






10. Volcanoes - hot springs - geysers






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






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






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






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






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






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






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






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






19. Hydrogen sulfide pollution - sources are often national treasures






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






21. Solid biomass to liquid biomass with chemicals and heat






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






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






24. Semi-permeable dams






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






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






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






28. Pockets of hot water/steam underground






29. Soft coal - reduced water (3%)






30. Difference between high and low tide






31. Solar energy heats water which turns a turbine






32. Water conservation - jobs - energy -






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






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






35. Burning rubbish/garbage






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






37. 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






38. Burning biomass






39. Bacteria ferments biomass with sugars






40. Off shore wind is the most efficient






41. Accumulation of organic material by living things






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






43. Compacting biomass through high temperatures - VED goes up






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






45. Volumetric energy density






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






47. Replenish themselves or are continuously present






48. 3 factors that affect volatility






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






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