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

2. The past climate...for this reason - both keep good records of climate change.






3. US is responsible for ___ of the total CO2






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






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






6. If the mean annual air temperature is only slightly below 0 degrees C - permafrost will form only in spots that are sheltered.






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






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






9. Radiation absorbed by atmospheric greenhouse gases?






10. Sea ice extent in Antarctica is rapidly reducing. Seasonal variability. People - Animals and Ice






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






12. 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






13. Summer increase in cloud cover - Winter decrease in cloud cover.

14. Really measures volume.






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






16. The Earth emits this.






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






18. Closed talik can develop when lakes fill in with sediment and become deposits of dead plant material (bog).






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






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






21. 240 w/m squared






22. The order of 1 m/year. Melting is ten times more.






23. Where does the ozone protect us?






24. 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.






25. Absolute thresholds - Monthly maximums and minimums - Threshold departures - Percentile departure - Atmospheric Water Vapor: More water vapor in the air - warmer nights!






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






27. High cloud has a _____ effect and cool cloud has a ____ effect






28. Ocean retains ____ CO2






29. How often does El Nio occur?






30. Amount of light absorbed by atmosphere






31. When meltwater seeps through a flowing glacier - it can lubricate the base and hasten the glacier's seaward flow.






32. Rain is getting harder and the rain is lasting longer since the past couple of decades and will continue for that amount.






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






34. 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






35. 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






36. Precipitation intensity will rise ___ for every 1 OC of warming.






37. High clouds are a ____ feedback; larger greenhouse warming - Clouds reflect shortwave radiation but also absorb longwave radiation






38. 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






39. LW - SW - 55% absorbed by surface






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






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






42. 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.






43. Due to a set of mutually reinforcing processes - climate change appears to be progressing in the arctic more quickly than in any other region on Earth.






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






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






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






47. 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.






48. Greenhouse gases are mixed in the ____






49. 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.






50. 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.
