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






2. More common






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






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






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






6. The order of 1 m/year. Melting is ten times more.






7. How often does El Nio occur?






8. Where do greenhouse gases warm up the Earth?






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






10. Amount of light absorbed by atmosphere






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






12. 342 W/m squared - DWEC - These things reflect sunlight (30%): water vapor - clouds - dust particles - earth's surface






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






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






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






16. Closed talik can develop when lakes fill in with sediment and become deposits of dead plant material (bog).






17. 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.






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






19. Heat is provided by outside sources that flow down the continental slope to reach the deepest part of the glacier. High pressure decreases the melting point and favors melting.






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






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






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






23. Industry 40% - Buildings 31% - Transportations 22% - Agriculture 4%






24. 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






25. 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






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






27. Permafrost- A frozen soil






28. A thick - floating slab of freshwater ice extending from coast to coast.






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






30. When inversion breaks up _______________. - Consequently - anything that breaks inversions or makes them form less often could produce major ground level warming.






31. 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.






32. 23 -45 degrees. The Larger the tilt the larger the variability of the seasons.

33. 1. Altimetry survey 2. Time-variable gravity 3. Ice motion + Regional Climate Modeling






34. The heat input is either driven by the 1- thermohaline circulation associated with sea ice formation. The direct influx of intermediate warmth water.






35. Really measures volume.






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






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






38. The last portion of a glacier grounded to bedrock - after this line there are ice shelves.






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






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






41. Greenhouse gases are mixed in the ____






42. Set up in 1988 by WMO and UNEP.






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






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






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






46. 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.






47. LW - SW - 55% absorbed by surface






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






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