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






2. Burning wood






3. Bacteria ferments biomass with sugars






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






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






6. Volumetric energy density






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






8. Accumulation of organic material by living things






9. Crops and crop residue






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






11. Semi-permeable dams






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






13. Volcanoes - hot springs - geysers






14. 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






15. Pockets of hot water/steam underground






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






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






18. Solid biomass to liquid biomass with chemicals and heat






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






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






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






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






23. Replenish themselves or are continuously present






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






25. Compacting biomass through high temperatures - VED goes up






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






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






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






29. Hydrogen sulfide pollution - sources are often national treasures






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






31. Solar cells to convert solar energy directly to electricity






32. Hard coal - highest rank - 96% carbon






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






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






35. Burning to get heat and electricity






36. Difference between high and low tide






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






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






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






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






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






42. Off shore wind is the most efficient






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






44. 3 factors that affect volatility






45. 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






46. Water conservation - jobs - energy -






47. Solar energy heats water which turns a turbine






48. Soft coal - reduced water (3%)






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






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