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. 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






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






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






4. Difference between high and low tide






5. Hard coal - highest rank - 96% carbon






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






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






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






9. Solid biomass to liquid biomass with chemicals and heat






10. Soft coal - reduced water (3%)






11. Hydrogen sulfide pollution - sources are often national treasures






12. Bacteria ferments biomass with sugars






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






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






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






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






17. Compacting biomass through high temperatures - VED goes up






18. Volcanoes - hot springs - geysers






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






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






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






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






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






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






25. Off shore wind is the most efficient






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






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






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






29. Solar energy heats water which turns a turbine






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






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






32. Solar cells to convert solar energy directly to electricity






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






34. 3 factors that affect volatility






35. Burning wood






36. Burning biomass






37. 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






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






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






40. Burning rubbish/garbage






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






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






43. Water conservation - jobs - energy -






44. Pockets of hot water/steam underground






45. Burning to get heat and electricity






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






47. Semi-permeable dams






48. Crops and crop residue






49. Replenish themselves or are continuously present






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