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






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






3. Burning biomass






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






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






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






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






8. Crops and crop residue






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






10. Burning wood






11. Hydrogen sulfide pollution - sources are often national treasures






12. Volumetric energy density






13. Accumulation of organic material by living things






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






15. 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






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






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






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






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






20. Hard coal - highest rank - 96% carbon






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






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






23. Solid biomass to liquid biomass with chemicals and heat






24. Solar cells to convert solar energy directly to electricity






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






26. Water conservation - jobs - energy -






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






28. Compacting biomass through high temperatures - VED goes up






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






30. Difference between high and low tide






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






32. Replenish themselves or are continuously present






33. Off shore wind is the most efficient






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






35. Burning to get heat and electricity






36. 3 factors that affect volatility






37. Semi-permeable dams






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






39. Volcanoes - hot springs - geysers






40. 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






41. Bacteria ferments biomass with sugars






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






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






44. Solar energy heats water which turns a turbine






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






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






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






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






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






50. Burning rubbish/garbage
