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. Soft coal - reduced water (3%)






2. Volumetric energy density






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






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






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






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






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






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






9. Solar energy heats water which turns a turbine






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






11. Solid biomass to liquid biomass with chemicals and heat






12. Replenish themselves or are continuously present






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






14. Burning rubbish/garbage






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






16. Burning biomass






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






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






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






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






21. Difference between high and low tide






22. Burning to get heat and electricity






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






24. Pockets of hot water/steam underground






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






26. 3 factors that affect volatility






27. Hydrogen sulfide pollution - sources are often national treasures






28. 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






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






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






31. Solar cells to convert solar energy directly to electricity






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






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






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






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






36. Compacting biomass through high temperatures - VED goes up






37. Water conservation - jobs - energy -






38. Semi-permeable dams






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






40. Bacteria ferments biomass with sugars






41. Crops and crop residue






42. 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






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






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






45. Accumulation of organic material by living things






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






47. Off shore wind is the most efficient






48. Burning wood






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






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