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






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






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






4. Semi-permeable dams






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






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






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






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






9. Crops and crop residue






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






11. Solid biomass to liquid biomass with chemicals and heat






12. Off shore wind is the most efficient






13. Hydrogen sulfide pollution - sources are often national treasures






14. 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






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






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






17. Burning rubbish/garbage






18. Solar cells to convert solar energy directly to electricity






19. Volcanoes - hot springs - geysers






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






21. Solar energy heats water which turns a turbine






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






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






24. Volumetric energy density






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






26. 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






27. Water conservation - jobs - energy -






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






29. Burning to get heat and electricity






30. Burning biomass






31. Difference between high and low tide






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






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






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






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






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






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






38. Pockets of hot water/steam underground






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






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






41. Soft coal - reduced water (3%)






42. Replenish themselves or are continuously present






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






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






45. Bacteria ferments biomass with sugars






46. 3 factors that affect volatility






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






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






49. Accumulation of organic material by living things






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