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






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






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






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






5. Water conservation - jobs - energy -






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






7. 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






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






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






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






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






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






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






14. Burning rubbish/garbage






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






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






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. Hydrogen sulfide pollution - sources are often national treasures






19. Solar cells to convert solar energy directly to electricity






20. 3 factors that affect volatility






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






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






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






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






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






26. Bacteria ferments biomass with sugars






27. Off shore wind is the most efficient






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






29. Solar energy heats water which turns a turbine






30. Volumetric energy density






31. 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






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






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






34. Replenish themselves or are continuously present






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






36. Solid biomass to liquid biomass with chemicals and heat






37. Difference between high and low tide






38. Accumulation of organic material by living things






39. Compacting biomass through high temperatures - VED goes up






40. Pockets of hot water/steam underground






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






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






43. Soft coal - reduced water (3%)






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






45. Burning to get heat and electricity






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






47. Hard coal - highest rank - 96% carbon






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






49. Semi-permeable dams






50. Volcanoes - hot springs - geysers
