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. Water conservation - jobs - energy -






2. Hard coal - highest rank - 96% carbon






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






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






5. Solid biomass to liquid biomass with chemicals and heat






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






7. Burning biomass






8. Hydrogen sulfide pollution - sources are often national treasures






9. Off shore wind is the most efficient






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






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






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






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






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






15. Solar cells to convert solar energy directly to electricity






16. Volumetric energy density






17. Bacteria ferments biomass with sugars






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






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






20. Pockets of hot water/steam underground






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






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






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






24. Difference between high and low tide






25. Soft coal - reduced water (3%)






26. Semi-permeable dams






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






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






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






30. 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






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






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






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






34. Accumulation of organic material by living things






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






36. Burning to get heat and electricity






37. Replenish themselves or are continuously present






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






39. 3 factors that affect volatility






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






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






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






43. Burning wood






44. Crops and crop residue






45. 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






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






47. Solar energy heats water which turns a turbine






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






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






50. Compacting biomass through high temperatures - VED goes up
