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. Replenish themselves or are continuously present






2. Pockets of hot water/steam underground






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






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






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






6. 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






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






8. 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






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






10. 3 factors that affect volatility






11. Hard coal - highest rank - 96% carbon






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






13. Solid biomass to liquid biomass with chemicals and heat






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






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






16. Accumulation of organic material by living things






17. Burning to get heat and electricity






18. Compacting biomass through high temperatures - VED goes up






19. Bacteria ferments biomass with sugars






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






21. Semi-permeable dams






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






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






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






25. Solar energy heats water which turns a turbine






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






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






28. Water conservation - jobs - energy -






29. Hydrogen sulfide pollution - sources are often national treasures






30. Soft coal - reduced water (3%)






31. Off shore wind is the most efficient






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






33. Volumetric energy density






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






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






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






37. Crops and crop residue






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






39. Difference between high and low tide






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






41. Solar cells to convert solar energy directly to electricity






42. Burning biomass






43. Burning wood






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






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






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






47. Volcanoes - hot springs - geysers






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






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






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