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






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






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






4. 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






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






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






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






8. Hydrogen sulfide pollution - sources are often national treasures






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






10. Bacteria ferments biomass with sugars






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






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






13. Hard coal - highest rank - 96% carbon






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






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






16. 3 factors that affect volatility






17. Volcanoes - hot springs - geysers






18. Volumetric energy density






19. 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






20. Replenish themselves or are continuously present






21. Solar cells to convert solar energy directly to electricity






22. Compacting biomass through high temperatures - VED goes up






23. Soft coal - reduced water (3%)






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






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






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






27. Burning biomass






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






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






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






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






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






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






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






35. Water conservation - jobs - energy -






36. Burning to get heat and electricity






37. Difference between high and low tide






38. Burning wood






39. Semi-permeable dams






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






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






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






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






44. Pockets of hot water/steam underground






45. Solid biomass to liquid biomass with chemicals and heat






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






47. Off shore wind is the most efficient






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






49. Solar energy heats water which turns a turbine






50. Crops and crop residue
