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






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






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






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






6. Solar cells to convert solar energy directly to electricity






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






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






9. Hard coal - highest rank - 96% carbon






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






11. Accumulation of organic material by living things






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






13. Solid biomass to liquid biomass with chemicals and heat






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






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






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






17. Hydrogen sulfide pollution - sources are often national treasures






18. Replenish themselves or are continuously present






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






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






21. Burning to get heat and electricity






22. Solar energy heats water which turns a turbine






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






24. 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






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






26. Semi-permeable dams






27. Off shore wind is the most efficient






28. Bacteria ferments biomass with sugars






29. 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






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






31. Burning biomass






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






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






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






35. Burning rubbish/garbage






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






37. Crops and crop residue






38. Water conservation - jobs - energy -






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






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






41. Volcanoes - hot springs - geysers






42. Pockets of hot water/steam underground






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






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






45. Volumetric energy density






46. Difference between high and low tide






47. Burning wood






48. Soft coal - reduced water (3%)






49. 3 factors that affect volatility






50. Compacting biomass through high temperatures - VED goes up
