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. Accumulation of organic material by living things






2. Solar cells to convert solar energy directly to electricity






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






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






5. Burning wood






6. Compacting biomass through high temperatures - VED goes up






7. 3 factors that affect volatility






8. 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






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






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






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






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






13. Semi-permeable dams






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






15. 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






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






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






18. Replenish themselves or are continuously present






19. Solid biomass to liquid biomass with chemicals and heat






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






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. Volumetric energy density






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






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






25. Pockets of hot water/steam underground






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






27. Water conservation - jobs - energy -






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






29. Hydrogen sulfide pollution - sources are often national treasures






30. Hard coal - highest rank - 96% carbon






31. Soft coal - reduced water (3%)






32. Burning biomass






33. Off shore wind is the most efficient






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






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






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






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






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






39. Burning rubbish/garbage






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






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






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






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






44. Burning to get heat and electricity






45. Difference between high and low tide






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






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






48. Bacteria ferments biomass with sugars






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






50. Volcanoes - hot springs - geysers
