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






2. Burning rubbish/garbage






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






4. Accumulation of organic material by living things






5. 3 factors that affect volatility






6. Volcanoes - hot springs - geysers






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






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






9. Difference between high and low tide






10. Solar energy heats water which turns a turbine






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






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






13. Burning to get heat and electricity






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






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






16. Off shore wind is the most efficient






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






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






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






21. 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






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






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






24. 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






25. Hard coal - highest rank - 96% carbon






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






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






28. Volumetric energy density






29. Burning wood






30. Bacteria ferments biomass with sugars






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






32. Water conservation - jobs - energy -






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






34. Semi-permeable dams






35. Pockets of hot water/steam underground






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






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






38. Solid biomass to liquid biomass with chemicals and heat






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






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






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






42. Hydrogen sulfide pollution - sources are often national treasures






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






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






45. Compacting biomass through high temperatures - VED goes up






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






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






48. Replenish themselves or are continuously present






49. Crops and crop residue






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