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 -No direct pollution though! Bird death ray - Startup cost






2. Water conservation - jobs - energy -






3. Semi-permeable dams






4. Pockets of hot water/steam underground






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






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






7. Crops and crop residue






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






9. Compacting biomass through high temperatures - VED goes up






10. Volumetric energy density






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






12. 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






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






14. Solar energy heats water which turns a turbine






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






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






17. Off shore wind is the most efficient






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






19. Hydrogen sulfide pollution - sources are often national treasures






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






21. Hard coal - highest rank - 96% carbon






22. Soft coal - reduced water (3%)






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






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






25. Solid biomass to liquid biomass with chemicals and heat






26. Accumulation of organic material by living things






27. Burning biomass






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






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






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






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






32. Difference between high and low tide






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






34. Burning to get heat and electricity






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






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






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






38. Bacteria ferments biomass with sugars






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






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






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






42. 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






43. 3 factors that affect volatility






44. Volcanoes - hot springs - geysers






45. Burning rubbish/garbage






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






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






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






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






50. Replenish themselves or are continuously present
