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. Most of the deserts are around 30 N and 30 S - where sinking air predominates






2. 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:






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






4. Nitrogen (N2 78%) and Oxygen (O2 21%) - Their linear 2 atom molecular structure






5. Long time series started in the '70s and yielding good data in the '90s - Detects elevation with high accuracy: 10 cm precision (laser) to 1 m (radar) - 2/3 Gravity Surveys (GRACE) - Weighing the total mass every 30 days - Direct monthly estimate






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






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






8. Land Based Ecosystems retain ____ CO2.






9. 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) -






10. 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.






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






12. 23 -45 degrees. The Larger the tilt the larger the variability of the seasons.

13. Ocean retains ____ CO2






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

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






16. 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






17. The depletion of stratospheric ozone layer in Antarctica in Springtime (august through October)






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






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






20. 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.






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






22. Where do greenhouse gases warm up the Earth?






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






24. How often does El Nio occur?






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






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






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






28. 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.






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






30. Amount of light absorbed by surface






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






32. High vs low






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






34. 85%






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






36. ~15% of incident solar energy (albedo 85)






37. 240 w/m squared






38. 1. Land usage changes 2. Seasonal timing 3. Rising CO2 levels may be a factor






39. A process whereby slabs of ice at the glacier margin mechanically fracture and detach from the main ice mass -






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






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






42. Greenhouse gases are mixed in the ____






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






44. Antarctica - stratosphere - Sep-Oct






45. Longwave radiation - any radiation with a long wave will heat up quickly.






46. 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.






47. 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






48. 342 W/m squared - DWEC - These things reflect sunlight (30%): water vapor - clouds - dust particles - earth's surface






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






50. Where does the ozone protect us?
