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






2. Crops and crop residue






3. 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






4. 3 factors that affect volatility






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






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






7. Solar cells to convert solar energy directly to electricity






8. Accumulation of organic material by living things






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






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






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






12. Hard coal - highest rank - 96% carbon






13. Bacteria ferments biomass with sugars






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






15. Hydrogen sulfide pollution - sources are often national treasures






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






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






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






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






20. Volcanoes - hot springs - geysers






21. Burning biomass






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






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






24. Burning wood






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






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






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






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






29. Burning to get heat and electricity






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






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






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






33. Water conservation - jobs - energy -






34. Replenish themselves or are continuously present






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






36. Soft coal - reduced water (3%)






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






38. Solar energy heats water which turns a turbine






39. Difference between high and low tide






40. Volumetric energy density






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






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. Burning rubbish/garbage






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






45. 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






46. Compacting biomass through high temperatures - VED goes up






47. Solid biomass to liquid biomass with chemicals and heat






48. Pockets of hot water/steam underground






49. Off shore wind is the most efficient






50. Semi-permeable dams
