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. Hydrogen sulfide pollution - sources are often national treasures






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






4. Difference between high and low tide






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






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






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






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






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






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






11. Replenish themselves or are continuously present






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






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






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






15. Solid biomass to liquid biomass with chemicals and heat






16. Solar energy heats water which turns a turbine






17. Burning wood






18. Water conservation - jobs - energy -






19. Pockets of hot water/steam underground






20. Semi-permeable dams






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






22. Crops and crop residue






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






24. Burning to get heat and electricity






25. 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






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






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






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






29. Soft coal - reduced water (3%)






30. Accumulation of organic material by living things






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






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






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






34. Burning rubbish/garbage






35. Compacting biomass through high temperatures - VED goes up






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






37. 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






38. 3 factors that affect volatility






39. Solar cells to convert solar energy directly to electricity






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






41. Burning biomass






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






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






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






45. Hard coal - highest rank - 96% carbon






46. Bacteria ferments biomass with sugars






47. Off shore wind is the most efficient






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






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






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