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






2. Forms in a mosaic of favoured locations.






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






4. 1. Keeps the ocean and the earth cooler 2. Coastal impacts of ice: prevents waves from eroding coastlines and protects from storms. 3. Ecological importance of ice: a. Most visibly for the many fish - birds - and mammal species that live in - on - or






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






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






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






8. More common






9. In ________- inversion layer is more common in the Arctic






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






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






12. Peru and Ecuador to the equatorial central pacific - Causes irregular warming in sea surface






13. Cooler water and drought conditions.






14. High vs low






15. 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!






16. 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






17. Over the Northern Hemisphere than the tropics.






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






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






20. 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






21. A process whereby slabs of ice at the glacier margin mechanically fracture and detach from the main ice mass -






22. 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






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






24. Amount of light absorbed by surface






25. South polar vortex - Temperatures drop below 80O Celsius in the lower stratosphere - At these temperatures the chemicals in the stratosphere freeze and form Polar Stratospheric Clouds (PSCS) - These increase the concentration of CFCs in turn destroyi






26. 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






27. Like weighing oneself on the scale.






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






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






30. Set up in 1988 by WMO and UNEP.






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






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






33. The difference between the incoming radiation energy and the outgoing radiation energy - A measure of the net energy.






34. 10 : 1 - grounding ; surface






35. Radiation that comes from the Sun - Visible light - 'near infrared' - ultraviolet radiation.






36. Some parts of the planet are dry because of their location: most of the deserts are around 30 N and 30 S - where sinking air predominates






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






38. 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






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






40. Antarctica - stratosphere - Sep-Oct






41. 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.






42. Floating extensions are ice shelves - rivers of ice are ice streams or outlet glaciers - the junctions with the ocean are called the grounding line.






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






44. 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) -






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






46. 1.4 USA - 57 m total sea level equivalent






47. 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






48. Measures input and output.






49. 85%






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