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. Number of days that exceed a given temperature






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






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






4. Precipitation extremes appear to generally increase across the planet at especially high latitudes.






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






6. Is defined usually on the basis of the degree of dryness (in comparison to some 'normal' or average amount






7. 85%






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






9. 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.






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






11. Deep tropics between 15O N and 15 O S are quite rainy on yearly average. In these regions - rising air predominates.






12. 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.






13. 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






14. LW - SW - 55% absorbed by surface






15. CO2 - CH4 - O3 - H2O - N2O - CFCs






16. 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.






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






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






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






20. Really measures volume.






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






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






23. Forms in a mosaic of favoured locations.






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






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






26. Temperature needed to melt at depth is much lower than that needed to melt at the surface.






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






28. 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






29. 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






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






31. 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.






32. Warming- positive feedback - Cooling- negative feedback.






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






34. 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.






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






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






37. 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.






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






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






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






41. Same amount of H2O - Mass does not change - Density of ice < density of water - Volume of ice > volume of water






42. Peru and Ecuador to the equatorial central pacific - Causes irregular warming in sea surface






43. The Earth emits this.






44. Melting Point decreases






45. Atmosphere retains ____ CO2






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






47. 20% human produced CO2 emissions. Tropical forests hold around 50% of the carbon present in vegetation on Earth.






48. Greenhouse gases are mixed in the ____






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






50. 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
