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. Replenish themselves or are continuously present






2. Burning biomass






3. Water conservation - jobs - energy -






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






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






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






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






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






9. Solar energy heats water which turns a turbine






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






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






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






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






14. 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






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






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






17. 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






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






19. Burning to get heat and electricity






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






21. 3 factors that affect volatility






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






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






24. Soft coal - reduced water (3%)






25. Burning wood






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






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






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






29. Bacteria ferments biomass with sugars






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






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






32. Difference between high and low tide






33. Solid biomass to liquid biomass with chemicals and heat






34. Pockets of hot water/steam underground






35. Burning rubbish/garbage






36. Accumulation of organic material by living things






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






38. Solar cells to convert solar energy directly to electricity






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






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






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






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






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






44. Semi-permeable dams






45. Hydrogen sulfide pollution - sources are often national treasures






46. Compacting biomass through high temperatures - VED goes up






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






48. Hard coal - highest rank - 96% carbon






49. Volumetric energy density






50. Off shore wind is the most efficient
