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






2. Compacting biomass through high temperatures - VED goes up






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






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






5. Burning to get heat and electricity






6. 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






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






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






9. Volumetric energy density






10. Solar energy heats water which turns a turbine






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






12. Soft coal - reduced water (3%)






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






14. Crops and crop residue






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






16. Burning wood






17. Bacteria ferments biomass with sugars






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






19. 3 factors that affect volatility






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






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






22. Difference between high and low tide






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






24. 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






25. Off shore wind is the most efficient






26. Solar cells to convert solar energy directly to electricity






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






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






29. Burning rubbish/garbage






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






31. Pockets of hot water/steam underground






32. Solid biomass to liquid biomass with chemicals and heat






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






34. Hydrogen sulfide pollution - sources are often national treasures






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






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






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






38. Replenish themselves or are continuously present






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






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






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






42. Water conservation - jobs - energy -






43. Burning biomass






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






45. Semi-permeable dams






46. Hard coal - highest rank - 96% carbon






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






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






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






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