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






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






3. Soft coal - reduced water (3%)






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






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






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






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






8. Compacting biomass through high temperatures - VED goes up






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






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






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






12. 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






13. Volcanoes - hot springs - geysers






14. Hydrogen sulfide pollution - sources are often national treasures






15. Replenish themselves or are continuously present






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






17. Pockets of hot water/steam underground






18. Off shore wind is the most efficient






19. Accumulation of organic material by living things






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






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






22. Solar cells to convert solar energy directly to electricity






23. Difference between high and low tide






24. Bacteria ferments biomass with sugars






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






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






27. Burning to get heat and electricity






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






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






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






31. Crops and crop residue






32. Hard coal - highest rank - 96% carbon






33. Solar energy heats water which turns a turbine






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






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






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






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






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






39. 3 factors that affect volatility






40. 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






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






42. Water conservation - jobs - energy -






43. Semi-permeable dams






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






45. Burning biomass






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






47. Volumetric energy density






48. Burning wood






49. Burning rubbish/garbage






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