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






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






3. 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






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






5. Off shore wind is the most efficient






6. Burning rubbish/garbage






7. Hydrogen sulfide pollution - sources are often national treasures






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






9. Compacting biomass through high temperatures - VED goes up






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






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






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






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






14. Accumulation of organic material by living things






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






16. Volumetric energy density






17. 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






18. Semi-permeable dams






19. Soft coal - reduced water (3%)






20. Volcanoes - hot springs - geysers






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






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






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






24. Hard coal - highest rank - 96% carbon






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






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






27. Difference between high and low tide






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






29. Water conservation - jobs - energy -






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






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






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






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






34. Pockets of hot water/steam underground






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






36. 3 factors that affect volatility






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






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






39. Bacteria ferments biomass with sugars






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






41. Burning to get heat and electricity






42. Crops and crop residue






43. Solar cells to convert solar energy directly to electricity






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






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






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






47. Burning wood






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






49. Solar energy heats water which turns a turbine






50. Replenish themselves or are continuously present
