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






2. Ice sheets have a very ____ Albedo






3. 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






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






5. 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






6. Is unfrozen ground that is exposed to the ground surface and to a larger mass of unfrozen ground beneath it.






7. Unfrozen ground that is found within a mass of permafrost






8. 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






9. Water vapor means more water up in the clouds and less in the ground!






10. 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.






11. In average: +1% in respect to 100 years ago.






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






13. 85%






14. Forms in a mosaic of favoured locations.






15. Is defined usually on the basis of the degree of dryness (in comparison to some 'normal' or average amount






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






17. Temperature needed to melt at depth is much lower than that needed to melt at the surface.






18. 1.4 USA - 57 m total sea level equivalent






19. How much is the planet really warming?






20. A mass of land ice - continental or sub-continental in extent - and thick enough to cover most of the underlying bedrock topography - If you have a warm ocean - it will melt the ice sheet. Its shape is mainly determined by the dynamics of its outward






21. 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






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






23. When inversion breaks up _______________. - Consequently - anything that breaks inversions or makes them form less often could produce major ground level warming.






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






25. Refers to the irregular warming in the Sea Surface Temperatures (SST) from the coasts of Peru and Ecuador to the equatorial central Pacific - the Southern Oscillation






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






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






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






29. Closed talik can develop when lakes fill in with sediment and become deposits of dead plant material (bog).






30. Set up in 1988 by WMO and UNEP.






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






32. Radiation absorbed by atmospheric greenhouse gases?






33. Amount of light absorbed by surface






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






35. 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






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






37. 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






38. Prolonged period of excessively hot weather - Which may be accompanied by high humidity.






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






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






41. 10 : 1 - grounding ; surface






42. US is responsible for ___ of the total CO2






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






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






45. 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






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






47. Permafrost- A frozen soil






48. Melting Point decreases






49. Less frequent and weaker






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