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. CO2 ____ in winter in the NH and ____ decreases during the 'greening season'






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






3. LW - SW - 55% absorbed by surface






4. Antarctica - stratosphere - Sep-Oct






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






6. 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






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

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






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






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






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






12. Where do greenhouse gases warm up the Earth?






13. Occurs when there is not enough water available for a particular crop to grow at a particular time.Typically seen after!meteorological drought (when rainfall decreases) but before a hydrological drought






14. Like weighing oneself on the scale.






15. 342 W/m squared - DWEC - These things reflect sunlight (30%): water vapor - clouds - dust particles - earth's surface






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. Number of days that exceed a given temperature






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






19. Land Based Ecosystems retain ____ CO2.






20. 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






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






22. Greenhouse gases are a ___ portion of the atmosphere






23. Ozone layer in high stratosphere (25-40 km altitude) absorbs about 95-99% of ultraviolet radiation.






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






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






26. Where does the ozone protect us?






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






28. 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






29. Ice flowing from the middle of Greenland to the edges and melting. 90 feet a day- speed that ice is moving.






30. 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.






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






32. 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.






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






34. Sea ice extent in Antarctica is rapidly reducing. Seasonal variability. People - Animals and Ice






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






36. Cooler water and drought conditions.






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






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






39. Warming- positive feedback - Cooling- negative feedback.






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






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






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






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






44. 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






45. 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






46. Absolute thresholds - Monthly maximums and minimums - Threshold departures - Percentile departure - Atmospheric Water Vapor: More water vapor in the air - warmer nights!






47. Higher temperature increases atmospheric water vapor @ global scale more water vapor in the air that causes nights to stay warmer.






48. High cloud has a _____ effect and cool cloud has a ____ effect






49. On a clear cold day - the thin layer of air hugging the ground is called inversion. This layer is much cooler than the air a few hundred meters above it.






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