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






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






3. Volumetric energy density






4. Solar energy heats water which turns a turbine






5. 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






6. Solar cells to convert solar energy directly to electricity






7. Volcanoes - hot springs - geysers






8. Burning rubbish/garbage






9. Hard coal - highest rank - 96% carbon






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






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






12. Burning wood






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






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






15. Soft coal - reduced water (3%)






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






17. Compacting biomass through high temperatures - VED goes up






18. Hydrogen sulfide pollution - sources are often national treasures






19. Burning biomass






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






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






22. Bacteria ferments biomass with sugars






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






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






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






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






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






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






29. Burning to get heat and electricity






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






31. Solid biomass to liquid biomass with chemicals and heat






32. Crops and crop residue






33. 3 factors that affect volatility






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






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






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






37. Pockets of hot water/steam underground






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






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






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






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






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






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






44. Difference between high and low tide






45. Semi-permeable dams






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






47. 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






48. Accumulation of organic material by living things






49. Water conservation - jobs - energy -






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