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






2. Hard coal - highest rank - 96% carbon






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






4. Hydrogen sulfide pollution - sources are often national treasures






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






6. Soft coal - reduced water (3%)






7. Compacting biomass through high temperatures - VED goes up






8. Burning to get heat and electricity






9. Solid biomass to liquid biomass with chemicals and heat






10. Volumetric energy density






11. Solar energy heats water which turns a turbine






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






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






14. Burning wood






15. Bacteria ferments biomass with sugars






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






17. Replenish themselves or are continuously present






18. Pockets of hot water/steam underground






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






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






21. 3 factors that affect volatility






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






23. Burning rubbish/garbage






24. Water conservation - jobs - energy -






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






26. Accumulation of organic material by living things






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






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






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






30. Burning biomass






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






32. Semi-permeable dams






33. 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






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






35. Solar cells to convert solar energy directly to electricity






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






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






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






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






40. 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






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






42. Off shore wind is the most efficient






43. Difference between high and low tide






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






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






46. Volcanoes - hot springs - geysers






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






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






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






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