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. 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.






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






3. Industry 40% - Buildings 31% - Transportations 22% - Agriculture 4%






4. 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.






5. 23 -45 degrees. The Larger the tilt the larger the variability of the seasons.

6. Descending Air dry - Convection cells are wet.






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






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






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






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






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

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






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






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






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






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






17. Permafrost- A frozen soil






18. Is unfrozen ground that is exposed to the ground surface and to a larger mass of unfrozen ground beneath it.






19. 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






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






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






22. Is defined usually on the basis of the degree of dryness (in comparison to some 'normal' or average amount






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






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






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






26. 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.






27. Just remember the general direction of the circulation - Rising northern pacific. You start in between Greenland and Europe (youngest water) - Oldest water is in the Pacific Ocean - Salty water> fresh water - Cold Water > Warm Water






28. Forms in a mosaic of favoured locations.






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






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






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






32. 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






33. 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.






34. ~10% of incident solar energy (albedo 90)






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






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






37. 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) -






38. 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.






39. 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






40. O Unfrozen soil that stays within the permafrost.






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

44. Ocean retains ____ CO2






45. 2ppm of the atmosphere - less than 20% of greenhouse gases - 1/3 greenhouse gases effect of CO2

47. Like weighing oneself on the scale.






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