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 -No direct pollution though! Bird death ray - Startup cost






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






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






4. Replenish themselves or are continuously present






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






6. Burning rubbish/garbage






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






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






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






10. 3 factors that affect volatility






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






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






13. Hydrogen sulfide pollution - sources are often national treasures






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






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






16. Solar cells to convert solar energy directly to electricity






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






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






19. Burning to get heat and electricity






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






21. 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






22. Burning wood






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






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






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






26. Solid biomass to liquid biomass with chemicals and heat






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






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






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






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






31. Hard coal - highest rank - 96% carbon






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






33. Compacting biomass through high temperatures - VED goes up






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






35. Pockets of hot water/steam underground






36. Soft coal - reduced water (3%)






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






38. 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






39. Off shore wind is the most efficient






40. Burning biomass






41. Volumetric energy density






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






43. Accumulation of organic material by living things






44. Bacteria ferments biomass with sugars






45. Semi-permeable dams






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






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






48. Difference between high and low tide






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






50. Volcanoes - hot springs - geysers
