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. Near the poles - tight openings - high tidal range






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






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






5. Crops and crop residue






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






7. Solar energy heats water which turns a turbine






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






9. Semi-permeable dams






10. Burning biomass






11. Hard coal - highest rank - 96% carbon






12. Volumetric energy density






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






14. Replenish themselves or are continuously present






15. Compacting biomass through high temperatures - VED goes up






16. Solar cells to convert solar energy directly to electricity






17. Burning to get heat and electricity






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






19. 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






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






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






22. Difference between high and low tide






23. 3 factors that affect volatility






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






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






26. Burning wood






27. Bacteria ferments biomass with sugars






28. Off shore wind is the most efficient






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






30. Hydrogen sulfide pollution - sources are often national treasures






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






32. 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






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






34. Pockets of hot water/steam underground






35. Accumulation of organic material by living things






36. Water conservation - jobs - energy -






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






38. Volcanoes - hot springs - geysers






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






40. Solid biomass to liquid biomass with chemicals and heat






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






42. Burning rubbish/garbage






43. Soft coal - reduced water (3%)






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






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






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






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






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






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






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