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. 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






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






3. Hydrogen sulfide pollution - sources are often national treasures






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






5. Volcanoes - hot springs - geysers






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






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






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






9. Crops and crop residue






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






11. Semi-permeable dams






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






13. Burning biomass






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






15. Burning wood






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






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






19. Solar cells to convert solar energy directly to electricity






20. 3 factors that affect volatility






21. Volumetric energy density






22. Difference between high and low tide






23. Off shore wind is the most efficient






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






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






26. Pockets of hot water/steam underground






27. Bacteria ferments biomass with sugars






28. Solar energy heats water which turns a turbine






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






30. Burning rubbish/garbage






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






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






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






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






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






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






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






38. Compacting biomass through high temperatures - VED goes up






39. Accumulation of organic material by living things






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






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






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






43. Burning to get heat and electricity






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






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






46. Soft coal - reduced water (3%)






47. Replenish themselves or are continuously present






48. Water conservation - jobs - energy -






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






50. Solid biomass to liquid biomass with chemicals and heat
