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






2. Land Based Ecosystems retain ____ CO2.






3. Descending Air dry - Convection cells are wet.






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






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






6. 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






7. 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






8. When inversion breaks up _______________. - Consequently - anything that breaks inversions or makes them form less often could produce major ground level warming.






9. Forms from frozen ocean water - Floats on the ocean surface - Grows over the winter - melts in the summer






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






11. The large-scale ocean circulation that moves water between the deep and surface ocean which effects salinity and temperature change - Supplies heat to the polar-regions.






12. 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) -






13. 85%






14. Greenhouse gases are mixed in the ____






15. Antarctica - stratosphere - Sep-Oct






16. Is best viewed as a combination of...- Natural Variability - Associated with atmospheric circulation patterns - Growing Radiative Forcing - Associated with rising concentrations of atmospheric greenhouse gases - Strongly suggests a human influence.






17. In average: +1% in respect to 100 years ago.






18. 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.






19. Temperature needed to melt at depth is much lower than that needed to melt at the surface.






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






21. In troposphere = greenhouse warming gas - However - most of it is in the stratosphere.






22. 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






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






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






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






26. Number of days that exceed a given temperature






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

28. Amount of light absorbed by atmosphere






29. Pockets of ice in the topmost permafrost caused by thawing which create an underground lake.






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






31. Like weighing oneself on the scale.






32. Positive Albedo Feedback - increase in temperature melts ice and snow reduces albedo increases temperature melts ice and snow reduces albedo... ETC






33. Warming- positive feedback - Cooling- negative feedback.






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






35. 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






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






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






38. Water vapor means more water up in the clouds and less in the ground!






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






40. 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.






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






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






43. Amount of light absorbed by surface






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






45. Sea ice and continental ice. This is caused by Atmospheric warming triggers.






46. Permafrost- A frozen soil






47. 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






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






49. 20% human produced CO2 emissions. Tropical forests hold around 50% of the carbon present in vegetation on Earth.






50. 23 -45 degrees. The Larger the tilt the larger the variability of the seasons.
