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. In _______ - the inversions are less frequent and weaker in the Arctic.






2. Like weighing oneself on the scale.






3. Massive cooldown has allowed colder conditions to persist leading to cfcs stabilizing leading to ozone depletion. Later - more warming will lead to more moisture in the air which will lead to more snowfall!






4. Atmosphere retains ____ CO2






5. Most of the deserts are around 30 N and 30 S - where sinking air predominates






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






7. The heat input is either driven by the 1- thermohaline circulation associated with sea ice formation. The direct influx of intermediate warmth water.






8. High clouds are a ____ feedback; larger greenhouse warming - Clouds reflect shortwave radiation but also absorb longwave radiation






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






10. 1. Altimetry survey 2. Time-variable gravity 3. Ice motion + Regional Climate Modeling






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






12. Greenhouse gases are mixed in the ____






13. Set up in 1988 by WMO and UNEP.






14. Heat is provided by outside sources that flow down the continental slope to reach the deepest part of the glacier. High pressure decreases the melting point and favors melting.






15. Tundra absorbs more energy than ice and snow but less than scrubs and forest - and with those plants migrating towards the north - they will further contribute ot absorb more energy.






16. How much is the planet really warming?






17. 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






18. Industry 40% - Buildings 31% - Transportations 22% - Agriculture 4%






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






20. The transition of a substance from the solid phase directly to the vapor phase - or vice versa - without passing through an intermediate liquid phase.






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






22. O Unfrozen soil that stays within the permafrost.






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






24. The land-surface configuration that results from the melting of ground ice in a region where permafrost degrades is called Thermokarst.






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






26. Summer increase in cloud cover - Winter decrease in cloud cover.

27. Sea ice extent in Antarctica is rapidly reducing. Seasonal variability. People - Animals and Ice






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






29. 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.






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






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






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






33. 2ppm of the atmosphere - less than 20% of greenhouse gases - 1/3 greenhouse gases effect of CO2






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






35. Forms in a mosaic of favoured locations.






36. Changes over time in the highest and lowest single temperature observed during a given month of the year.






37. 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






38. Just remember the general direction of the circulation - Rising northern pacific. You start in between Greenland and Europe (youngest water) - Oldest water is in the Pacific Ocean - Salty water> fresh water - Cold Water > Warm Water






39. Ice melting rapidly? What type causes sea level to rise? What have been the main contributors to sea level rise so far? What are the impacts of melting ice? - On nature - On humans






40. Really measures volume.






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






42. Due to a set of mutually reinforcing processes - climate change appears to be progressing in the arctic more quickly than in any other region on Earth.






43. Number of days that exceed a given temperature






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






45. 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.






46. Warming- positive feedback - Cooling- negative feedback.






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






48. Ocean retains ____ CO2






49. Arctic troposphere is thinner (8-10 km) than the tropics...The depth of the atmospheric layer is much shallower in the Arctic - It takes less energy to warm the Arctic rather than the Tropics - Same as heating an apartment vs. a house






50. 342 W/m squared - DWEC - These things reflect sunlight (30%): water vapor - clouds - dust particles - earth's surface
