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






2. Crops and crop residue






3. Burning to get heat and electricity






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






5. Burning wood






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






7. Solar cells to convert solar energy directly to electricity






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






9. Compacting biomass through high temperatures - VED goes up






10. Burning rubbish/garbage






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






12. 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






13. Semi-permeable dams






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






15. Accumulation of organic material by living things






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






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






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






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






20. Pockets of hot water/steam underground






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






22. Bacteria ferments biomass with sugars






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






24. Difference between high and low tide






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






26. Volumetric energy density






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






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






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






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






31. Solid biomass to liquid biomass with chemicals and heat






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






33. Water conservation - jobs - energy -






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






35. 3 factors that affect volatility






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






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






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






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






40. Hydrogen sulfide pollution - sources are often national treasures






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






42. Hard coal - highest rank - 96% carbon






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






44. 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






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






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






47. Burning biomass






48. Replenish themselves or are continuously present






49. Volcanoes - hot springs - geysers






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