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






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






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






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






5. Replenish themselves or are continuously present






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






7. Crops and crop residue






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






9. Bacteria ferments biomass with sugars






10. Accumulation of organic material by living things






11. Off shore wind is the most efficient






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






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






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






15. Difference between high and low tide






16. Volcanoes - hot springs - geysers






17. Hard coal - highest rank - 96% carbon






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






19. Pockets of hot water/steam underground






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






21. Hydrogen sulfide pollution - sources are often national treasures






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






23. Burning to get heat and electricity






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






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






26. Burning rubbish/garbage






27. 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






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






29. Solar energy heats water which turns a turbine






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






31. Volumetric energy density






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






33. Burning biomass






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






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






36. Compacting biomass through high temperatures - VED goes up






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






38. Burning wood






39. Solar cells to convert solar energy directly to electricity






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






41. Soft coal - reduced water (3%)






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






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






44. Semi-permeable dams






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






46. 3 factors that affect volatility






47. Solid biomass to liquid biomass with chemicals and heat






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






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






50. Water conservation - jobs - energy -
