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. Pockets of hot water/steam underground






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






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






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






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






6. Solid biomass to liquid biomass with chemicals and heat






7. Semi-permeable dams






8. 3 factors that affect volatility






9. Solar cells to convert solar energy directly to electricity






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






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






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






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






14. Compacting biomass through high temperatures - VED goes up






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






16. Water conservation - jobs - energy -






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






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






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






20. Accumulation of organic material by living things






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






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






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






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






25. Solar energy heats water which turns a turbine






26. Volumetric energy density






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






28. Hydrogen sulfide pollution - sources are often national treasures






29. Crops and crop residue






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






31. Burning wood






32. Burning to get heat and electricity






33. 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






34. Burning biomass






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






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






37. Replenish themselves or are continuously present






38. Off shore wind is the most efficient






39. Volcanoes - hot springs - geysers






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






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






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






43. Bacteria ferments biomass with sugars






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






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. Difference between high and low tide






47. Burning rubbish/garbage






48. Hard coal - highest rank - 96% carbon






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






50. Soft coal - reduced water (3%)
