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. 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






2. 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.






3. Holds unique and key information - Are highly interconnected - Respond and drive climate change - Are the largest freshwater reservoirs of the planet - Ice cores tell us that in climate records - nothing is regular and ice sheet plays major role.






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






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






6. Greenhouse gases are mixed in the ____






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






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






9. Forms in a mosaic of favoured locations.






10. Melting Point decreases






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






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






13. 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






14. 1. We live in troposphere. Greenhouse gases here warm up the Earth 2. Above stratosphere. The ozone in this layer protects us.






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






16. Betts et al found that: if CO-2 __________ this has a physiological effect on plant transpiration increased simulated runoff by 6% b. How? i. More CO2 1. Plants pores open less 2. This reduces transpiration 3. More water in the land surface






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






18. 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.






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






20. Descending Air dry - Convection cells are wet.






21. 10 : 1 - grounding ; surface






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






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






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






25. 78% nitrogen - 28% oxygen - Greenhouse gases: Have a more complex molecular structure and can absorb and re:radiate heat in all directions.






26. 20% human produced CO2 emissions. Tropical forests hold around 50% of the carbon present in vegetation on Earth.






27. Grounding line is the last portion of a glacier grounded to bedrock - after this line there are ice shelves - Glaciers contribute to sea level rise after passing the grounding line - Maximum thinning at grounding line.






28. Amount of light absorbed by atmosphere






29. 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!






30. Carbon dioxide - Methane - Ozone - Water Vapor - Few others - Most ___________________ are mixed in the troposphere (Except water vapor) - Water vapor is concentrated closer to the ground.






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






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






33. The order of 1 m/year. Melting is ten times more.






34. 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.






35. The air can hold less water vapor - Consequently - less water can be evaporated in the air - and only a small portion of energy is used in this process - Most of the energy that reaches the Arctic goes directly into warming the air






36. Warming- positive feedback - Cooling- negative feedback.






37. 240 w/m squared






38. 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






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

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






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






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






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






44. 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.






45. The buoyant force is equal to the weight of the displaced water.

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






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






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






49. Thawing permafrost weakens coastal lands. Risk of flooding in coastal wetlands. Pollution and toxins locked in the snow and ice will be released.






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