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. Burning wood






2. Off shore wind is the most efficient






3. Burning biomass






4. Hard coal - highest rank - 96% carbon






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






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






7. Soft coal - reduced water (3%)






8. Volcanoes - hot springs - geysers






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






10. Solar cells to convert solar energy directly to electricity






11. Water conservation - jobs - energy -






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






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






14. Burning rubbish/garbage






15. Compacting biomass through high temperatures - VED goes up






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






17. Solar energy heats water which turns a turbine






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






19. Crops and crop residue






20. Semi-permeable dams






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






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






23. Solid biomass to liquid biomass with chemicals and heat






24. Burning to get heat and electricity






25. Accumulation of organic material by living things






26. Volumetric energy density






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






28. 3 factors that affect volatility






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






30. 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






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






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






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






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






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






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






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






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






39. Hydrogen sulfide pollution - sources are often national treasures






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






41. Difference between high and low tide






42. Replenish themselves or are continuously present






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






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






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






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






47. Pockets of hot water/steam underground






48. Bacteria ferments biomass with sugars






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






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