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






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






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






4. Pockets of hot water/steam underground






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






6. 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






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






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






9. Volcanoes - hot springs - geysers






10. Compacting biomass through high temperatures - VED goes up






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






12. Hard coal - highest rank - 96% carbon






13. Water conservation - jobs - energy -






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






15. Crops and crop residue






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






17. Volumetric energy density






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






19. Accumulation of organic material by living things






20. Bacteria ferments biomass with sugars






21. Burning wood






22. Replenish themselves or are continuously present






23. Burning to get heat and electricity






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






25. Soft coal - reduced water (3%)






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






27. Solar cells to convert solar energy directly to electricity






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






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






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






31. Solar energy heats water which turns a turbine






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






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






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






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






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






37. 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






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






39. 3 factors that affect volatility






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






41. Solid biomass to liquid biomass with chemicals and heat






42. Hydrogen sulfide pollution - sources are often national treasures






43. Off shore wind is the most efficient






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






45. Burning biomass






46. Burning rubbish/garbage






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






48. Difference between high and low tide






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






50. Semi-permeable dams
