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






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






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






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






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






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. Semi-permeable dams






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






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






11. Volcanoes - hot springs - geysers






12. Burning rubbish/garbage






13. Crops and crop residue






14. Solid biomass to liquid biomass with chemicals and heat






15. Accumulation of organic material by living things






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






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






18. Volumetric energy density






19. Pockets of hot water/steam underground






20. Burning to get heat and electricity






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






22. 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






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






24. Burning wood






25. Solar energy heats water which turns a turbine






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






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






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






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






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






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






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






33. Compacting biomass through high temperatures - VED goes up






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






35. Replenish themselves or are continuously present






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






37. Solar cells to convert solar energy directly to electricity






38. Bacteria ferments biomass with sugars






39. Hard coal - highest rank - 96% carbon






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






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






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






43. Water conservation - jobs - energy -






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






45. 3 factors that affect volatility






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






47. 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






48. Burning biomass






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






50. Hydrogen sulfide pollution - sources are often national treasures
