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






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






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






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






6. Hard coal - highest rank - 96% carbon






7. Burning rubbish/garbage






8. Burning wood






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






10. Volumetric energy density






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






12. Bacteria ferments biomass with sugars






13. Solid biomass to liquid biomass with chemicals and heat






14. Water conservation - jobs - energy -






15. Crops and crop residue






16. Volcanoes - hot springs - geysers






17. 3 factors that affect volatility






18. Replenish themselves or are continuously present






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






20. Difference between high and low tide






21. Burning to get heat and electricity






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






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






24. Semi-permeable dams






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






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






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






28. Hydrogen sulfide pollution - sources are often national treasures






29. Soft coal - reduced water (3%)






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






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






32. Burning biomass






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






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






35. Solar cells to convert solar energy directly to electricity






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. Accumulation of organic material by living things






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






39. Compacting biomass through high temperatures - VED goes up






40. Off shore wind is the most efficient






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






42. Solar energy heats water which turns a turbine






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






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






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






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






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






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






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






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