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. Water conservation - jobs - energy -






2. Off shore wind is the most efficient






3. Burning biomass






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






5. 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






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






7. Difference between high and low tide






8. Semi-permeable dams






9. Volcanoes - hot springs - geysers






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






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






12. Solar cells to convert solar energy directly to electricity






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






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






15. 3 factors that affect volatility






16. Burning to get heat and electricity






17. Solar energy heats water which turns a turbine






18. Burning wood






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






20. Solid biomass to liquid biomass with chemicals and heat






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






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






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






24. Burning rubbish/garbage






25. Compacting biomass through high temperatures - VED goes up






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






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






28. Accumulation of organic material by living things






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






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






31. Volumetric energy density






32. Pockets of hot water/steam underground






33. Bacteria ferments biomass with sugars






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






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






36. Replenish themselves or are continuously present






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






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






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






40. Crops and crop residue






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






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






43. Hydrogen sulfide pollution - sources are often national treasures






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






45. 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






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






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






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






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






50. Hard coal - highest rank - 96% carbon
