Subjects : literacy, 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. Extent will increase the warming because less energy will be reflected back to the atmosphere by the ice and more will be absorbed by the ocean.






2. 10 : 1 - grounding ; surface






3. Changes in the Earth's solar radiation levels can impact the climate. Shortterm warming cycles on Earth.






4. More common






5. Number of days that land among the hottest of all days in that month's long-term record.






6. Slow steady decline of about 4% per decade in the total volume of Earth's stratospheric ozone.






7. Absolute thresholds - Monthly maximums and minimums - Threshold departures - Percentile departure - Atmospheric Water Vapor: More water vapor in the air - warmer nights!






8. Sea ice and continental ice. This is caused by Atmospheric warming triggers.






9. Soil at or below the freezing point of water for two or more years - Can be: Terrestrial - Subsea - Can be: Continuous: exists across a landscape as an unbroken layer. More than 90% is frozen - Discontinuous






10. Precipitation intensity will rise ___ for every 1 OC of warming.






11. Wet gets _____ - dry gets ____ - Wet - 50ON (sub polar) Canada - N Europe - Russia - Tropical area- monsoon (rainforest) - Drier - Subtropics - Australia - S. Africa - Mediterranean - Caribbean - Mexico - SW US






12. A climate forcing agent formed through the incomplete combustion of fossil fuels - biofuel - and biomass; emitted both anthropogenic:ally and naturally.






13. The order of 1 m/year. Melting is ten times more.






14. Average molecular life span is less than 10 years - Major sources: Wetlands and oceans - Raising cattle and landfills.






15. Industrial product - 300 ppb (parts per billion)






16. Volcanic eruptions - Sunspots - Wobbly Earth






17. Nitrogen (N2 78%) and Oxygen (O2 21%) - Their linear 2 atom molecular structure






18. Ocean retains ____ CO2






19. Laser radar - H V - Long time series - high accuracy - Density






20. How much is the planet really warming?






21. Amount of light absorbed by atmosphere






22. he increase of ozone concentration in the atmosphere helps ____ our planet






23. A dome shaped cover of perennial ice and snow.






24. Over the past century what has happened to the Earth's temperature?






25. The major distinction between the Protocol and the Convention is that while the Convention encouraged industrialized countries to stabilize GHG emissions - the Protocol commits them to do so.






26. Arctic warms faster than other parts of the globe in response to a given increase in greenhouse gasses - More direct route to warming - In the Arctic a greater fraction of any increase in radiation absorbed by the surface goes directly into warming t






27. Water vapor - 36-70% - carbon dioxide - 9-26% - methane - 4-9% - ozone - 3-7%






28. Deep tropics between 15O N and 15 O S are quite rainy on yearly average. In these regions - rising air predominates.






29. Atmospheric Cooling - Both negative (stabilizing) feedbacks - It is not happening now - but it has happened in the past - Ice-albedo feedback was the dominant feedback during the ice ages.






30. Where does the ozone protect us?






31. Under higher pressure the melting point decreases ____ - The pressure comes from the weight of the ice shelf.






32. Longwave radiation - any radiation with a long wave will heat up quickly.






33. CO2 GHG forcing - H2O - dominant/major GHG






34. This is the total mass change - difference between input and outputs—snow accumulation-ablation.






35. Greenhouse gases are a ___ portion of the atmosphere






36. Number of days that exceed a given temperature






37. They saw a massive thinning of the ice where it enters into the ocean - This is due to the pronounced melting of the ice once it is in contact with the ocean. Melt rates of 25 m/year near the grounding lines and more than 10 m/year on average.






38. Warming- positive feedback - Cooling- negative feedback.






39. 23 -45 degrees. The Larger the tilt the larger the variability of the seasons.

40. Radiation absorbed by atmospheric greenhouse gases?






41. The amount of light reflected by an object.






42. Taliks are found under lakes because of the ability of water to store and vertically transfer heat energy - Vertical extent of the taliks found under lakes is related to the depth and volume of the overlying water body.






43. Permafrost- A frozen soil






44. Higher temperature increases atmospheric water vapor @ global scale more water vapor in the air that causes nights to stay warmer.






45. Atmosphere retains ____ CO2






46. Reduction of snow and ice cover - Changes in atmospheric circulation.






47. Refers to a body of freshwater - usually shallow - formed in a depression by melt water from thawing permafrost.






48. US is responsible for ___ of the total CO2






49. x7 smaller - 7m total sea level equivalent.






50. Pockets of ice in the topmost permafrost caused by thawing which create an underground lake.
