Renewable And Nonrenewable Energy

Subject : science
Instructions:
  • Answer 50 questions in 30 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. Solar cells to convert solar energy directly to electricity






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






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






4. Burning rubbish/garbage






5. 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






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






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






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






9. Semi-permeable dams






10. Replenish themselves or are continuously present






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






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






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






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






15. Hydrogen sulfide pollution - sources are often national treasures






16. Difference between high and low tide






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






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






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






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






21. Accumulation of organic material by living things






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






23. Solar energy heats water which turns a turbine






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






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






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






27. Solid biomass to liquid biomass with chemicals and heat






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






29. Bacteria ferments biomass with sugars






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






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






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






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






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






35. Burning to get heat and electricity






36. Pockets of hot water/steam underground






37. Soft coal - reduced water (3%)






38. 3 factors that affect volatility






39. Water conservation - jobs - energy -






40. Crops and crop residue






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






42. Hard coal - highest rank - 96% carbon






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






44. Off shore wind is the most efficient






45. Volcanoes - hot springs - geysers






46. 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






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






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






49. Burning biomass






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