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






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






3. 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!






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






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






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






7. Warming- positive feedback - Cooling- negative feedback.






8. 10 : 1 - grounding ; surface






9. Number of days that exceed a given temperature






10. ~15% of incident solar energy (albedo 85)






11. 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






12. They saw a massive thinning of the ice where it enters into the ocean - This is due to the pronounced melting of the ice once it is in contact with the ocean. Melt rates of 25 m/year near the grounding lines and more than 10 m/year on average.






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






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






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






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






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






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

19. Over the Northern Hemisphere than the tropics.






20. Over the past century what has happened to the Earth's temperature?






21. 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






22. By contrast reflects only about 7% of solar radiation (Albedo~7%) - absorbing 93%.






23. Is not an externally imposed perturbation to the climate system.






24. Like weighing oneself on the scale.






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






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






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






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






29. The air can hold less water vapor - Consequently - less water can be evaporated in the air - and only a small portion of energy is used in this process - Most of the energy that reaches the Arctic goes directly into warming the air






30. 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






31. 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






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






33. 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






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






35. High vs low






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






37. Radiation absorbed by atmospheric greenhouse gases?






38. In troposphere = greenhouse warming gas - However - most of it is in the stratosphere.






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






40. 23 -45 degrees. The Larger the tilt the larger the variability of the seasons.

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






42. The Earth emits this.






43. O Unfrozen soil that stays within the permafrost.






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






45. Less frequent and weaker






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






47. Ice sheets have a very ____ Albedo






48. The buoyant force is equal to the weight of the displaced water.

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






50. Hydrological drought is associated with the effect of low rainfall on water levels in rivers -!reservoirs -!lakes and aquifers.
