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






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






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






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






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






6. 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






7. The depletion of stratospheric ozone layer in Antarctica in Springtime (august through October)






8. 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






9. Refers to a body of freshwater - usually shallow - formed in a depression by melt water from thawing permafrost.






10. The past climate...for this reason - both keep good records of climate change.






11. Laser radar - H V - Long time series - high accuracy - Density






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






13. CO2 GHG forcing - H2O - dominant/major GHG






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






15. LW - SW - 55% absorbed by surface






16. 342 W/m squared - DWEC - These things reflect sunlight (30%): water vapor - clouds - dust particles - earth's surface






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






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






19. Permafrost- A frozen soil






20. 78% nitrogen - 28% oxygen - Greenhouse gases: Have a more complex molecular structure and can absorb and re:radiate heat in all directions.






21. Atmosphere retains ____ CO2






22. When meltwater seeps through a flowing glacier - it can lubricate the base and hasten the glacier's seaward flow.






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






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






25. Antarctica - stratosphere - Sep-Oct






26. 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.






27. 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






28. x7 smaller - 7m total sea level equivalent.






29. Descending Air dry - Convection cells are wet.






30. 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






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






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






33. 10 : 1 - grounding ; surface






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






36. If the mean annual air temperature is only slightly below 0 degrees C - permafrost will form only in spots that are sheltered.






37. Over the past century what has happened to the Earth's temperature?






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






39. 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.






40. A climate forcing agent formed through the incomplete combustion of fossil fuels - biofuel - and biomass; emitted both anthropogenic:ally and naturally.






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






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






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






44. Like weighing oneself on the scale.






45. 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.






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






47. 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






48. Hydrological drought is associated with the effect of low rainfall on water levels in rivers -!reservoirs -!lakes and aquifers.






49. 23 -45 degrees. The Larger the tilt the larger the variability of the seasons.

50. Precipitation intensity will rise ___ for every 1 OC of warming.
