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






2. Solid biomass to liquid biomass with chemicals and heat






3. Off shore wind is the most efficient






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






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






6. Replenish themselves or are continuously present






7. Crops and crop residue






8. Burning wood






9. Difference between high and low tide






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






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






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






13. 3 factors that affect volatility






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






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






17. Volcanoes - hot springs - geysers






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






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






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






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






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






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






24. Burning rubbish/garbage






25. Solar energy heats water which turns a turbine






26. Compacting biomass through high temperatures - VED goes up






27. Water conservation - jobs - energy -






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






29. Accumulation of organic material by living things






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






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






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






33. Burning to get heat and electricity






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






35. Bacteria ferments biomass with sugars






36. Burning biomass






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






38. 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






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






40. Hydrogen sulfide pollution - sources are often national treasures






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






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






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






44. 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






45. Pockets of hot water/steam underground






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






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






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






49. Solar cells to convert solar energy directly to electricity






50. Hard coal - highest rank - 96% carbon
