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. 3 factors that affect volatility






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






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






4. Accumulation of organic material by living things






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






6. Bacteria ferments biomass with sugars






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






8. 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






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






10. Replenish themselves or are continuously present






11. Solar energy heats water which turns a turbine






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






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






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






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






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






17. Difference between high and low tide






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






19. Water conservation - jobs - energy -






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






21. Off shore wind is the most efficient






22. Solar cells to convert solar energy directly to electricity






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






24. Burning rubbish/garbage






25. Volcanoes - hot springs - geysers






26. Pockets of hot water/steam underground






27. Burning to get heat and electricity






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






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






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






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






32. Solid biomass to liquid biomass with chemicals and heat






33. Burning wood






34. Burning biomass






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






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






37. 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






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






39. Crops and crop residue






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






41. Semi-permeable dams






42. Hard coal - highest rank - 96% carbon






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






44. Hydrogen sulfide pollution - sources are often national treasures






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






46. Volumetric energy density






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






48. Compacting biomass through high temperatures - VED goes up






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






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