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






2. 10 : 1 - grounding ; surface






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






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






5. A naturally or artificially caused decrease in the thickness and/or areal extent of permafrost - It is caused by the deepening fo the active layer and the thawing of the adjacent permafrost.






6. South polar vortex - Temperatures drop below 80O Celsius in the lower stratosphere - At these temperatures the chemicals in the stratosphere freeze and form Polar Stratospheric Clouds (PSCS) - These increase the concentration of CFCs in turn destroyi






7. Ocean retains ____ CO2






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

9. 1.4 USA - 57 m total sea level equivalent






10. 20% human produced CO2 emissions. Tropical forests hold around 50% of the carbon present in vegetation on Earth.






11. 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






12. 1. They are the largest contributor to sea level rise 2. Can affect the thermohaline circulation (mainly in Greenland) 3. Are directly connected to climate change






13. 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






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






15. 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






16. ~10% of incident solar energy (albedo 90)






17. SALTY WATER = MORE DENSE - Maximum density at 4OC - This is why ice melting is a big deal; if the whole circle slows down - Ice bergs are fresh water higher sea level rise.






18. ~15% of incident solar energy (albedo 85)






19. Land Based Ecosystems retain ____ CO2.






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






21. Carbon dioxide - Methane - Ozone - Water Vapor - Few others - Most ___________________ are mixed in the troposphere (Except water vapor) - Water vapor is concentrated closer to the ground.






22. Cooler water and drought conditions.






23. Warming- positive feedback - Cooling- negative feedback.






24. Amount of light absorbed by atmosphere






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






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






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






28. 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.






29. Top layer of soil that thaws during the summer and freezes again during autumn. - Between 1 and 3 m thick.






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






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






32. Descending Air dry - Convection cells are wet.






33. Precipitation extremes appear to generally increase across the planet at especially high latitudes.






34. Permafrost- A frozen soil






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






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






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






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






39. 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.






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






41. 342 W/m squared - DWEC - These things reflect sunlight (30%): water vapor - clouds - dust particles - earth's surface






42. x7 smaller - 7m total sea level equivalent.






43. Where do greenhouse gases warm up the Earth?






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






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






46. How often does El Nio occur?






47. Average molecular life span is less than 10 years - Major sources: Wetlands and oceans - Raising cattle and landfills.






48. The Earth emits this.






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






50. 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.
