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






2. 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.






3. 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






4. High vs low






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






6. 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.






7. A mass of land ice - continental or sub-continental in extent - and thick enough to cover most of the underlying bedrock topography - If you have a warm ocean - it will melt the ice sheet. Its shape is mainly determined by the dynamics of its outward






8. 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.






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






10. 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.






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






12. O Unfrozen soil that stays within the permafrost.






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

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






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






16. Volcanic eruptions - Sunspots - Wobbly Earth






17. Cooler water and drought conditions.






18. 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.






19. Antarctica - stratosphere - Sep-Oct






20. 23 -45 degrees. The Larger the tilt the larger the variability of the seasons.

21. 1. Altimetry survey 2. Time-variable gravity 3. Ice motion + Regional Climate Modeling






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






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






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






25. 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:






26. Ice sheets have a very ____ Albedo






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






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






29. 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.






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






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






32. 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






33. 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






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






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






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






37. Set up in 1988 by WMO and UNEP.






38. Amount of light absorbed by surface






39. 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






40. Descending Air dry - Convection cells are wet.






41. Holds unique and key information - Are highly interconnected - Respond and drive climate change - Are the largest freshwater reservoirs of the planet - Ice cores tell us that in climate records - nothing is regular and ice sheet plays major role.






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






43. 342 W/m squared - DWEC - These things reflect sunlight (30%): water vapor - clouds - dust particles - earth's surface






44. 20% human produced CO2 emissions. Tropical forests hold around 50% of the carbon present in vegetation on Earth.






45. US is responsible for ___ of the total CO2






46. Prolonged period of excessively hot weather - Which may be accompanied by high humidity.






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






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






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






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