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. Where does the ozone protect us?






2. 10 : 1 - grounding ; surface






3. Help darkens the snow and ice surface - increasing the amount of energy that is absorbed.






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






5. 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.






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






7. The Earth emits this.






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






9. Arctic troposphere is thinner (8-10 km) than the tropics...The depth of the atmospheric layer is much shallower in the Arctic - It takes less energy to warm the Arctic rather than the Tropics - Same as heating an apartment vs. a house






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






11. Greenhouse gases are mixed in the ____






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






13. Ice sheets have a very ____ Albedo






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






15. 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






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






17. 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.






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






19. Total absorbed solar radiation






20. This is the total mass change - difference between input and outputs—snow accumulation-ablation.






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






22. How much is the planet really warming?






23. 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.






24. Set up in 1988 by WMO and UNEP.






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






26. 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






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






28. Reduction of Summer Sea- 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 - Snow and snow covered ice absorb 15% of incident solar energy - Ice absorbs 10% of inc






29. O Unfrozen soil that stays within the permafrost.






30. 78% nitrogen - 28% oxygen - Greenhouse gases: Have a more complex molecular structure and can absorb and re:radiate heat in all directions.






31. 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.






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






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






34. Less frequent and weaker






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






36. Pollution: heat and sunlight cook the air and the chemical compounds which are in it. This combines with the nitrogen oxide and creates 'smog'. This makes breathing difficult for those with respiratory ailments.






37. 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






38. Permafrost- A frozen soil






39. 1.4 USA - 57 m total sea level equivalent






40. How often does El Nio occur?






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






42. 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






43. What can cause a change in the Earth's climate balance?






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






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






46. Changes over time in the highest and lowest single temperature observed during a given month of the year.






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






48. he increase of ozone concentration in the atmosphere helps ____ our planet






49. 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






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