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. 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






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






3. Hydrogen sulfide pollution - sources are often national treasures






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






5. Compacting biomass through high temperatures - VED goes up






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






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






8. Bacteria ferments biomass with sugars






9. Soft coal - reduced water (3%)






10. 3 factors that affect volatility






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






12. Burning wood






13. Solar cells to convert solar energy directly to electricity






14. Hard coal - highest rank - 96% carbon






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






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






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






18. Water conservation - jobs - energy -






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






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






21. 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






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






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






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






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






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






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






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






29. Volcanoes - hot springs - geysers






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






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






32. Burning to get heat and electricity






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






34. Crops and crop residue






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






36. Difference between high and low tide






37. Burning biomass






38. Off shore wind is the most efficient






39. Solar energy heats water which turns a turbine






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






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






42. Burning rubbish/garbage






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






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






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






46. Pockets of hot water/steam underground






47. Accumulation of organic material by living things






48. Solid biomass to liquid biomass with chemicals and heat






49. Replenish themselves or are continuously present






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