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






2. 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






3. 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.






4. LW - SW - 55% absorbed by surface






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






6. 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






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






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






9. 85%






10. Clouds 40~90% - Vegetation 10~15%






11. 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.






12. ~10% of incident solar energy (albedo 90)






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






14. 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






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






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






17. Total absorbed solar radiation






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






19. Over the Northern Hemisphere than the tropics.






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






21. 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.






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






23. Forms in a mosaic of favoured locations.






24. Ice melting rapidly? What type causes sea level to rise? What have been the main contributors to sea level rise so far? What are the impacts of melting ice? - On nature - On humans






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






26. 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.






27. Where do greenhouse gases warm up the Earth?






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






29. A dome shaped cover of perennial ice and snow.






30. If the Earth is warmer - are we going to have the Hadley cell stronger or weaker? Hotter = heat rises which increases the circulation.






31. Rain is getting harder and the rain is lasting longer since the past couple of decades and will continue for that amount.






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






33. The large-scale ocean circulation that moves water between the deep and surface ocean which effects salinity and temperature change - Supplies heat to the polar-regions.






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






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






36. 1. Altimetry survey 2. Time-variable gravity 3. Ice motion + Regional Climate Modeling






37. 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






38. Amount of light absorbed by surface






39. A thick - floating slab of freshwater ice extending from coast to coast.






40. Sea ice - Glaciers and Ice sheets - Alaska- ice glaciers - Greenland- ice sheets






41. Under higher pressure the melting point decreases ____ - The pressure comes from the weight of the ice shelf.






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






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






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






45. 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!






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






47. 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






48. Extent 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.






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






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