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. Burning to get heat and electricity






2. 3 factors that affect volatility






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






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






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






6. Semi-permeable dams






7. Water conservation - jobs - energy -






8. Burning biomass






9. Difference between high and low tide






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






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






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






13. Solar cells to convert solar energy directly to electricity






14. 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






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






16. Off shore wind is the most efficient






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






18. Crops and crop residue






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






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






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






22. Solar energy heats water which turns a turbine






23. Compacting biomass through high temperatures - VED goes up






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






25. Hydrogen sulfide pollution - sources are often national treasures






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






27. Burning rubbish/garbage






28. Pockets of hot water/steam underground






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






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






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






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






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






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






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






36. 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






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






38. Accumulation of organic material by living things






39. Hard coal - highest rank - 96% carbon






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






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






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






43. Volumetric energy density






44. Volcanoes - hot springs - geysers






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






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






47. Solid biomass to liquid biomass with chemicals and heat






48. Burning wood






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






50. Replenish themselves or are continuously present
