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. Crops and crop residue






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






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






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






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






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






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






8. Burning rubbish/garbage






9. Solar cells to convert solar energy directly to electricity






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






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






12. Difference between high and low tide






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






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






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






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






17. Bacteria ferments biomass with sugars






18. Solid biomass to liquid biomass with chemicals and heat






19. Off shore wind is the most efficient






20. Replenish themselves or are continuously present






21. 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






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






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






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






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






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






27. Semi-permeable dams






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






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






30. 3 factors that affect volatility






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






32. Burning wood






33. Pockets of hot water/steam underground






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






35. Burning to get heat and electricity






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






37. Hard coal - highest rank - 96% carbon






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






39. Water conservation - jobs - energy -






40. Solar energy heats water which turns a turbine






41. Volcanoes - hot springs - geysers






42. Volumetric energy density






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






44. Soft coal - reduced water (3%)






45. Hydrogen sulfide pollution - sources are often national treasures






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






47. Compacting biomass through high temperatures - VED goes up






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






49. 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






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