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. 10 : 1 - grounding ; surface






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






3. Top layer of soil that thaws during the summer and freezes again during autumn. - Between 1 and 3 m thick.






4. Is not an externally imposed perturbation to the climate system.






5. ~10% of incident solar energy (albedo 90)






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






7. Number of days when temperatures climb above average by a fixed amount.






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






9. Greenhouse gases are a ___ portion of the atmosphere






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






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

12. 85%






13. Greenhouse gases are mixed in the ____






14. Forms in a mosaic of favoured locations.






15. What can cause a change in the Earth's climate balance?






16. Where does the ozone protect us?






17. Trade winds blow from East to West - Pool of warm water in the west - Meanwhile deep colder water rises up in the Eastern Pacific - The sea level is ~ 50-60 cm higher in Western Pacific (Indonesia) than in the Eastern Pacific (South America/Peru) -






18. CO2 ____ in winter in the NH and ____ decreases during the 'greening season'






19. Forms from frozen ocean water - Floats on the ocean surface - Grows over the winter - melts in the summer






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






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






22. 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.






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






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






25. O Climate change in the Arctic is occurring now - Changes have been huge already






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






27. 1. They are the largest contributor to sea level rise 2. Can affect the thermohaline circulation (mainly in Greenland) 3. Are directly connected to climate change






28. Sea ice - Continental ice sheets - Permafrost (frozen soil) - Mountain glaciers - Snow cover






29. SALTY WATER = MORE DENSE - Maximum density at 4OC - This is why ice melting is a big deal; if the whole circle slows down - Ice bergs are fresh water higher sea level rise.






30. Climate models suggest once the sea ice cover is thinned sufficiently - a strong kick from natural variability could initiate a rapid slide towards ice-free conditions in the summer.






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






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






33. Ice sheets have a very ____ Albedo






34. 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.






35. The amount of light reflected by an object.






36. At the bottom of the ice sheets the temperature doesn't necessarily have to be above 0... it could _____ more easily because of the water






37. Ocean retains ____ CO2






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






39. The large-scale ocean circulation that moves water between the deep and surface ocean which effects salinity and temperature change - Supplies heat to the polar-regions.






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






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






42. Fresh snow and snow-covered sea ice may have an albedo higher than 80% - even when melting in the summer. Sea ice has a higher albedo and can absorb as little as 10% of the solar energy. On average - sea ice albedo is around 85%






43. SMB- mass balance due to processes that affect the surface of the ice sheet. Precipitation- evapotranspiration-runoff-blowing snow etc.






44. The Day After Tomorrow - Circulation will slow by 10% to 50% in the next century






45. Help darkens the snow and ice surface - increasing the amount of energy that is absorbed.






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






47. 1. Land usage changes 2. Seasonal timing 3. Rising CO2 levels may be a factor






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






49. Low clouds are a ____ feedback; they will reflect more sunlight. Clouds reflect shortwave radiation but also absorb longwave radiation






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