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. 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.






2. Industrial product - 300 ppb (parts per billion)






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






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






5. 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






6. 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






7. Less frequent and weaker






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






9. Just remember the general direction of the circulation - Rising northern pacific. You start in between Greenland and Europe (youngest water) - Oldest water is in the Pacific Ocean - Salty water> fresh water - Cold Water > Warm Water






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






11. Radiation absorbed by atmospheric greenhouse gases?






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






13. Over the Northern Hemisphere than the tropics.






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






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






16. 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.






17. The amount of light reflected by an object.






18. Where does the ozone protect us?






19. Atmosphere retains ____ CO2






20. How much is the planet really warming?






21. Warming- positive feedback - Cooling- negative feedback.






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






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






24. 1.4 USA - 57 m total sea level equivalent






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






26. How often does El Nio occur?






27. 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






28. The major distinction between the Protocol and the Convention is that while the Convention encouraged industrialized countries to stabilize GHG emissions - the Protocol commits them to do so.






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






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






31. Poor resolution (200-400 km) does not allow us to distinguish glaciers and basins.






32. Set up in 1988 by WMO and UNEP.






33. Mass balance due to processes that affect the surface of the ice sheet. Precipitation-evapotranspiration-runoff-blowing snow etc...






34. 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






35. 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.






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






37. 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






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






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






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






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






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






43. 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.






44. Is best viewed as a combination of...- Natural Variability - Associated with atmospheric circulation patterns - Growing Radiative Forcing - Associated with rising concentrations of atmospheric greenhouse gases - Strongly suggests a human influence.






45. Frozen +2 years - Few centimeters to 1500 m






46. Forms in a mosaic of favoured locations.






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

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






49. Average molecular life span is less than 10 years - Major sources: Wetlands and oceans - Raising cattle and landfills.






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