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. Ocean retains ____ CO2






2. The Earth emits this.






3. 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.






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






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






6. Sea ice extent in Antarctica is rapidly reducing. Seasonal variability. People - Animals and Ice






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






8. 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






9. The Day After Tomorrow - Circulation will slow by 10% to 50% in the next century






10. Is unfrozen ground that is exposed to the ground surface and to a larger mass of unfrozen ground beneath it.






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






12. 20% human produced CO2 emissions. Tropical forests hold around 50% of the carbon present in vegetation on Earth.






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






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






15. 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.






16. High cloud has a _____ effect and cool cloud has a ____ effect






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






18. Number of days when temperatures climb above average by a fixed amount.






19. Less frequent and weaker






20. 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) -






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






22. 23 -45 degrees. The Larger the tilt the larger the variability of the seasons.

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






24. Reduction of Summer Sea- 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 - Snow and snow covered ice absorb 15% of incident solar energy - Ice absorbs 10% of inc






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






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






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






28. 342 W/m squared - DWEC - These things reflect sunlight (30%): water vapor - clouds - dust particles - earth's surface






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






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






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






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






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






34. A naturally or artificially caused decrease in the thickness and/or areal extent of permafrost - It is caused by the deepening fo the active layer and the thawing of the adjacent permafrost.






35. 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






36. Radiation absorbed by atmospheric greenhouse gases?






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






38. Nitrogen (N2 78%) and Oxygen (O2 21%) - Their linear 2 atom molecular structure






39. The high pressure decreases the melting point and favors melting - Melt water being less dense rises along the water column along the ice shelf bottom and may either escape the cavity or refreeze at some intermediate depth. Melting point decreases:






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






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






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






43. 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






44. Antarctica - stratosphere - Sep-Oct






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






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






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






48. Where do greenhouse gases warm up the Earth?






49. ~10% of incident solar energy (albedo 90)






50. Melting Point decreases
