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. Solar cells to convert solar energy directly to electricity






3. Crops and crop residue






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






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






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






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






8. Burning rubbish/garbage






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






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






11. 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






12. Hydrogen sulfide pollution - sources are often national treasures






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






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






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






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






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






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






19. Burning to get heat and electricity






20. Compacting biomass through high temperatures - VED goes up






21. Semi-permeable dams






22. Soft coal - reduced water (3%)






23. Burning wood






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






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






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






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






28. Water conservation - jobs - energy -






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






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






31. 3 factors that affect volatility






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






33. Hard coal - highest rank - 96% carbon






34. Volcanoes - hot springs - geysers






35. Solid biomass to liquid biomass with chemicals and heat






36. Difference between high and low tide






37. Off shore wind is the most efficient






38. Accumulation of organic material by living things






39. Volumetric energy density






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






41. Solar energy heats water which turns a turbine






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






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






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






45. Replenish themselves or are continuously present






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






47. Bacteria ferments biomass with sugars






48. Burning biomass






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






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