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. Tundra absorbs more energy than ice and snow but less than scrubs and forest - and with those plants migrating towards the north - they will further contribute ot absorb more energy.






2. 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.






3. Descending Air dry - Convection cells are wet.






4. Poor resolution (200-400 km) does not allow us to distinguish glaciers and basins.






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






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






7. 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






8. 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.






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






10. 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






11. Really measures volume.






12. 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) -






13. Atmospheric Cooling - Both negative (stabilizing) feedbacks - It is not happening now - but it has happened in the past - Ice-albedo feedback was the dominant feedback during the ice ages.






14. Where do greenhouse gases warm up the Earth?






15. Forms in a mosaic of favoured locations.






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






17. Total absorbed solar radiation






18. Volcanic eruptions - Sunspots - Wobbly Earth






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






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






21. 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






22. Atmosphere retains ____ CO2






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






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






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






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






27. Like weighing oneself on the scale.






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






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






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






31. The difference between the incoming radiation energy and the outgoing radiation energy - A measure of the net energy.






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






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






34. 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






35. 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.






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






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






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






39. Over the Northern Hemisphere than the tropics.






40. A climate forcing agent formed through the incomplete combustion of fossil fuels - biofuel - and biomass; emitted both anthropogenic:ally and naturally.






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






42. 240 w/m squared






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






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






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






46. US is responsible for ___ of the total CO2






47. The amount of light reflected by an object.






48. 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






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

50. All processes that add snow or ice to a glacier or to flowing ice or snow cover.
