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. 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






2. Crops and crop residue






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






4. Replenish themselves or are continuously present






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






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






7. Hard coal - highest rank - 96% carbon






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






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






10. Solar cells to convert solar energy directly to electricity






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






12. Bacteria ferments biomass with sugars






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






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






15. Burning rubbish/garbage






16. Volcanoes - hot springs - geysers






17. Water conservation - jobs - energy -






18. Accumulation of organic material by living things






19. Volumetric energy density






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






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






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






23. Solar energy heats water which turns a turbine






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






25. Soft coal - reduced water (3%)






26. Pockets of hot water/steam underground






27. Burning biomass






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






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






30. Off shore wind is the most efficient






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






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






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






34. Burning to get heat and electricity






35. 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






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






37. Compacting biomass through high temperatures - VED goes up






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






39. Difference between high and low tide






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






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






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






43. Semi-permeable dams






44. Hydrogen sulfide pollution - sources are often national treasures






45. 3 factors that affect volatility






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






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






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






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






50. Solid biomass to liquid biomass with chemicals and heat
