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






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






3. Pockets of hot water/steam underground






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






5. Burning biomass






6. Accumulation of organic material by living things






7. Bacteria ferments biomass with sugars






8. Burning rubbish/garbage






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






10. Solar energy heats water which turns a turbine






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






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






13. Solar cells to convert solar energy directly to electricity






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






15. Solid biomass to liquid biomass with chemicals and heat






16. Volcanoes - hot springs - geysers






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






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






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






20. Compacting biomass through high temperatures - VED goes up






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






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






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






24. 3 factors that affect volatility






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






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






27. Hard coal - highest rank - 96% carbon






28. Hydrogen sulfide pollution - sources are often national treasures






29. Crops and crop residue






30. Soft coal - reduced water (3%)






31. Burning to get heat and electricity






32. Difference between high and low tide






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






34. 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






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






36. Water conservation - jobs - energy -






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






38. Volumetric energy density






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






40. Burning wood






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






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






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






44. 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






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






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






47. Off shore wind is the most efficient






48. Semi-permeable dams






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






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