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. 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.






2. The air can hold less water vapor - Consequently - less water can be evaporated in the air - and only a small portion of energy is used in this process - Most of the energy that reaches the Arctic goes directly into warming the air






3. ~10% of incident solar energy (albedo 90)






4. On a clear cold day - the thin layer of air hugging the ground is called inversion. This layer is much cooler than the air a few hundred meters above it.






5. Amount of light absorbed by surface






6. High vs low






7. Pollution: heat and sunlight cook the air and the chemical compounds which are in it. This combines with the nitrogen oxide and creates 'smog'. This makes breathing difficult for those with respiratory ailments.






8. 10 : 1 - grounding ; surface






9. Positive Albedo Feedback - increase in temperature melts ice and snow reduces albedo increases temperature melts ice and snow reduces albedo... ETC






10. 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






11. Total absorbed solar radiation






12. Permafrost- A frozen soil






13. Like weighing oneself on the scale.






14. An area of unfrozen ground that is open to the ground surface but otherwise enclosed in permafrost.






15. Descending Air dry - Convection cells are wet.






16. A thick - floating slab of freshwater ice extending from coast to coast.






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






18. By contrast reflects only about 7% of solar radiation (Albedo~7%) - absorbing 93%.






19. Reduction of Summer Sea- 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 - Snow and snow covered ice absorb 15% of incident solar energy - Ice absorbs 10% of inc






20. Poor resolution (200-400 km) does not allow us to distinguish glaciers and basins.






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






22. Is best viewed as a combination of...- Natural Variability - Associated with atmospheric circulation patterns - Growing Radiative Forcing - Associated with rising concentrations of atmospheric greenhouse gases - Strongly suggests a human influence.






23. 240 w/m squared






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






25. The high pressure decreases the melting point and favors melting - Melt water being less dense rises along the water column along the ice shelf bottom and may either escape the cavity or refreeze at some intermediate depth. Melting point decreases:






26. More common






27. Antarctica - stratosphere - Sep-Oct






28. High cloud has a _____ effect and cool cloud has a ____ effect






29. Same amount of H2O - Mass does not change - Density of ice < density of water - Volume of ice > volume of water






30. Radiation absorbed by atmospheric greenhouse gases?






31. In troposphere = greenhouse warming gas - However - most of it is in the stratosphere.






32. CO2 - CH4 - O3 - H2O - N2O - CFCs






33. How often does El Nio occur?






34. Rainy on yearly average. In these regions - rising air predominates.






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






36. Occurs when there is not enough water available for a particular crop to grow at a particular time.Typically seen after!meteorological drought (when rainfall decreases) but before a hydrological drought






37. How much is the planet really warming?






38. Same as heating an apartment v home - Thinner atmosphere than tropics; warms faster.






39. The warmer the temperature - the deeper the active layer - thaws and refreezes every year - Permafrost below freezing for two or more years.






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






41. Clouds 40~90% - Vegetation 10~15%






42. Precipitation extremes appear to generally increase across the planet at especially high latitudes.






43. Much of the Arctic is overlain by snow and sea ice (land ice and sea ice) - It makes warming a much bigger deal in the Arctic






44. All processes that add snow or ice to a glacier or to flowing ice or snow cover.






45. The last portion of a glacier grounded to bedrock - after this line there are ice shelves.






46. Surface Mass Balance is of the order of _____ melting is ____ times more.






47. Really measures volume.






48. Less frequent and weaker






49. Troposphere - Stratosphere (Ozone Layer) - Mesosphere - Ionosphere






50. Long time series started in the '70s and yielding good data in the '90s - Detects elevation with high accuracy: 10 cm precision (laser) to 1 m (radar) - 2/3 Gravity Surveys (GRACE) - Weighing the total mass every 30 days - Direct monthly estimate
