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. Ice sheets have a very ____ Albedo






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






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






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

5. Warming- positive feedback - Cooling- negative feedback.






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






7. O The amount of energy moving in the form of photons or other elementary particles at a certain distance from the source per unit of area per second. Area/second






8. 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






9. Permafrost- A frozen soil






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






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






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






13. 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.






14. Much of the Arctic is overlain by snow and sea ice (land ice and sea ice) - It makes warming a much bigger deal in the Arctic






15. The past climate...for this reason - both keep good records of climate change.






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






17. 78% nitrogen - 28% oxygen - Greenhouse gases: Have a more complex molecular structure and can absorb and re:radiate heat in all directions.






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






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






20. 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.






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






22. 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.






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






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






25. 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.






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






27. Cooler water and drought conditions.






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






29. 85%






30. How often does El Nio occur?






31. ~15% of incident solar energy (albedo 85)






32. Ocean retains ____ CO2






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






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






35. 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:






36. O Unfrozen soil that stays within the permafrost.






37. 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






38. 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!






39. 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






40. Grounding line is the last portion of a glacier grounded to bedrock - after this line there are ice shelves - Glaciers contribute to sea level rise after passing the grounding line - Maximum thinning at grounding line.






41. The transition of a substance from the solid phase directly to the vapor phase - or vice versa - without passing through an intermediate liquid phase.






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






43. 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.






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






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






46. Where does the ozone protect us?






47. Volcanic eruptions - Sunspots - Wobbly Earth






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






49. Where do greenhouse gases warm up the Earth?






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