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. Volcanoes - hot springs - geysers






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






3. Hard coal - highest rank - 96% carbon






4. Burning wood






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






6. Difference between high and low tide






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






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






9. Burning biomass






10. 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






11. 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






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. Water conservation - jobs - energy -






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






16. Solar cells to convert solar energy directly to electricity






17. Burning rubbish/garbage






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






19. Solar energy heats water which turns a turbine






20. Compacting biomass through high temperatures - VED goes up






21. 3 factors that affect volatility






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






23. Soft coal - reduced water (3%)






24. Accumulation of organic material by living things






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






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






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






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






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






30. Volumetric energy density






31. Solid biomass to liquid biomass with chemicals and heat






32. Replenish themselves or are continuously present






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






34. Hydrogen sulfide pollution - sources are often national treasures






35. Crops and crop residue






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






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






38. Burning to get heat and electricity






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






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






41. Bacteria ferments biomass with sugars






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






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






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






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






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






47. Pockets of hot water/steam underground






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






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






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