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






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






4. Pockets of hot water/steam underground






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






6. Hydrogen sulfide pollution - sources are often national treasures






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






8. Semi-permeable dams






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






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






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






12. Solid biomass to liquid biomass with chemicals and heat






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






14. Volcanoes - hot springs - geysers






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






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






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






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






19. Compacting biomass through high temperatures - VED goes up






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






21. Solar energy heats water which turns a turbine






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






23. Burning rubbish/garbage






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






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






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






27. Water conservation - jobs - energy -






28. Crops and crop residue






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






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






31. Off shore wind is the most efficient






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






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






34. Bacteria ferments biomass with sugars






35. Difference between high and low tide






36. Accumulation of organic material by living things






37. Replenish themselves or are continuously present






38. Solar cells to convert solar energy directly to electricity






39. Burning to get heat and electricity






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






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






42. Volumetric energy density






43. Soft coal - reduced water (3%)






44. Burning biomass






45. 3 factors that affect volatility






46. 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






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






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






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






50. Hard coal - highest rank - 96% carbon
