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






2. 3 factors that affect volatility






3. Pockets of hot water/steam underground






4. Hard coal - highest rank - 96% carbon






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






6. Difference between high and low tide






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






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






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






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






11. Replenish themselves or are continuously present






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






13. Solar cells to convert solar energy directly to electricity






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






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






16. Volumetric energy density






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






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






19. Accumulation of organic material by living things






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






21. Burning biomass






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






23. Compacting biomass through high temperatures - VED goes up






24. 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






25. Hydrogen sulfide pollution - sources are often national treasures






26. Bacteria ferments biomass with sugars






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






28. Off shore wind is the most efficient






29. 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






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






31. Crops and crop residue






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






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






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






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






36. Burning rubbish/garbage






37. Water conservation - jobs - energy -






38. Soft coal - reduced water (3%)






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






40. Solid biomass to liquid biomass with chemicals and heat






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






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






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






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






45. Solar energy heats water which turns a turbine






46. Burning wood






47. Semi-permeable dams






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






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






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