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






2. Solar cells to convert solar energy directly to electricity






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






4. Volumetric energy density






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






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






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






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






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






10. Burning biomass






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






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






13. Water conservation - jobs - energy -






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






15. Solid biomass to liquid biomass with chemicals and heat






16. 3 factors that affect volatility






17. Replenish themselves or are continuously present






18. Volcanoes - hot springs - geysers






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






20. Compacting biomass through high temperatures - VED goes up






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






22. 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






23. Pockets of hot water/steam underground






24. Semi-permeable dams






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






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






27. Crops and crop residue






28. Hydrogen sulfide pollution - sources are often national treasures






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






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






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






32. Solar energy heats water which turns a turbine






33. Bacteria ferments biomass with sugars






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






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






36. Difference between high and low tide






37. Soft coal - reduced water (3%)






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






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






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






41. 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






42. Burning to get heat and electricity






43. Burning rubbish/garbage






44. Accumulation of organic material by living things






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






46. Off shore wind is the most efficient






47. Burning wood






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






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






50. Hard coal - highest rank - 96% carbon
