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






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






3. 78% nitrogen - 28% oxygen - Greenhouse gases: Have a more complex molecular structure and can absorb and re:radiate heat in all directions.






4. Warming- positive feedback - Cooling- negative feedback.






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






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






7. Changes in the Earth's solar radiation levels can impact the climate. Shortterm warming cycles on Earth.






8. Some parts of the planet are dry because of their location: most of the deserts are around 30 N and 30 S - where sinking air predominates






9. The amount of light reflected by an object.






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






11. Concentration of 380 ppmv - Have risen about 40% - Preindustrial~ 270~280 ppmv






12. 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






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






14. Unfrozen ground that is found within a mass of permafrost






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






16. High vs low






17. Melting Point decreases






18. 342 W/m squared - DWEC - These things reflect sunlight (30%): water vapor - clouds - dust particles - earth's surface






19. 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.






20. 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.






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






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






23. Surface Mass Balance is of the order of _____ melting is ____ times more.






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






25. Less frequent and weaker






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






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






28. 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.






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






30. 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:






31. In average: +1% in respect to 100 years ago.






32. 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.






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






34. Atmosphere retains ____ CO2






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






36. Really measures volume.






37. Ozone layer in high stratosphere (25-40 km altitude) absorbs about 95-99% of ultraviolet radiation.






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






39. 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






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






41. 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






42. Over the Northern Hemisphere than the tropics.






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






44. Amount of light absorbed by atmosphere






45. 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






46. 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






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






48. InSAR - +snow/-ice loss - ice dynamics - requires a lot of data.






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






50. Sea ice and continental ice. This is caused by Atmospheric warming triggers.
