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. Hydrogen sulfide pollution - sources are often national treasures






2. Solid biomass to liquid biomass with chemicals and heat






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






4. Burning biomass






5. 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






6. Burning rubbish/garbage






7. Off shore wind is the most efficient






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






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






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






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






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






13. Semi-permeable dams






14. Soft coal - reduced water (3%)






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






16. 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






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






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






19. Accumulation of organic material by living things






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






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






22. Burning wood






23. Hard coal - highest rank - 96% carbon






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






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






26. Water conservation - jobs - energy -






27. Volumetric energy density






28. 3 factors that affect volatility






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






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






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






32. Crops and crop residue






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






34. Solar energy heats water which turns a turbine






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






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






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






38. Pockets of hot water/steam underground






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






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






41. Compacting biomass through high temperatures - VED goes up






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






43. Solar cells to convert solar energy directly to electricity






44. Bacteria ferments biomass with sugars






45. Difference between high and low tide






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






47. Burning to get heat and electricity






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






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






50. Volcanoes - hot springs - geysers
