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. Antarctica - stratosphere - Sep-Oct






2. The past climate...for this reason - both keep good records of climate change.






3. ~15% of incident solar energy (albedo 85)






4. 78% nitrogen - 28% oxygen - Greenhouse gases: Have a more complex molecular structure and can absorb and re:radiate heat in all directions.






5. 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






6. Melting Point decreases






7. Refers to the irregular warming in the Sea Surface Temperatures (SST) from the coasts of Peru and Ecuador to the equatorial central Pacific - the Southern Oscillation






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






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






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






11. 2ppm of the atmosphere - less than 20% of greenhouse gases - 1/3 greenhouse gases effect of CO2






12. Number of days that exceed a given temperature






13. Grace - Tells us how much mass change we have - M - This is the measure of gravity (gives us the mass) - Directly measure mass change - Poor resolution






14. Where do greenhouse gases warm up the Earth?






15. 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






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






17. 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






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






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






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






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






22. Arctic troposphere is thinner (8-10 km) than the tropics...The depth of the atmospheric layer is much shallower in the Arctic - It takes less energy to warm the Arctic rather than the Tropics - Same as heating an apartment vs. a house






23. Ocean retains ____ CO2






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


25. Atmosphere retains ____ CO2






26. 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






27. SALTY WATER = MORE DENSE - Maximum density at 4OC - This is why ice melting is a big deal; if the whole circle slows down - Ice bergs are fresh water higher sea level rise.






28. ~10% of incident solar energy (albedo 90)






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






30. Sea ice - Continental ice sheets - Permafrost (frozen soil) - Mountain glaciers - Snow cover






31. 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.






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






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






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






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






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






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






38. O Unfrozen soil that stays within the permafrost.






39. 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.






40. 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






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






42. 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!






43. 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.






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






45. Land Based Ecosystems retain ____ CO2.






46. 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.






47. Ice sheets have a very ____ Albedo






48. 85%






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






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