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. 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.






2. 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






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






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






5. 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.






6. 23 -45 degrees. The Larger the tilt the larger the variability of the seasons.

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






8. Less frequent and weaker






9. LW - SW - 55% absorbed by surface






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






11. The high pressure decreases the melting point and favors melting - Melt water being less dense rises along the water column along the ice shelf bottom and may either escape the cavity or refreeze at some intermediate depth. Melting point decreases:






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






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






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






15. Rain is getting harder and the rain is lasting longer since the past couple of decades and will continue for that amount.






16. Really measures volume.






17. 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






18. 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






19. Land Based Ecosystems retain ____ CO2.






20. ~15% of incident solar energy (albedo 85)






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






22. Refers to a body of freshwater - usually shallow - formed in a depression by melt water from thawing permafrost.






23. Carbon dioxide - Methane - Ozone - Water Vapor - Few others - Most ___________________ are mixed in the troposphere (Except water vapor) - Water vapor is concentrated closer to the ground.






24. Fresh snow and snow-covered sea ice may have an albedo higher than 80% - even when melting in the summer. Sea ice has a higher albedo and can absorb as little as 10% of the solar energy. On average - sea ice albedo is around 85%






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






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






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






28. 20% human produced CO2 emissions. Tropical forests hold around 50% of the carbon present in vegetation on Earth.






29. Ocean retains ____ CO2






30. CO2 GHG forcing - H2O - dominant/major GHG






31. 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






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






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






34. Betts et al found that: if CO-2 __________ this has a physiological effect on plant transpiration increased simulated runoff by 6% b. How? i. More CO2 1. Plants pores open less 2. This reduces transpiration 3. More water in the land surface






35. 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.






36. Average molecular life span is less than 10 years - Major sources: Wetlands and oceans - Raising cattle and landfills.






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






38. 1.4 USA - 57 m total sea level equivalent






39. Slow steady decline of about 4% per decade in the total volume of Earth's stratospheric ozone.






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






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






42. The Earth emits this.






43. 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.






44. 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






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






46. 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






47. 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.






48. 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.






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






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