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. Amount of light absorbed by atmosphere






2. Same as heating an apartment v home - Thinner atmosphere than tropics; warms faster.






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






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






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






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






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






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






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






10. Massive cooldown has allowed colder conditions to persist leading to cfcs stabilizing leading to ozone depletion. Later - more warming will lead to more moisture in the air which will lead to more snowfall!






11. Forms in a mosaic of favoured locations.






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






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






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






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






16. 342 W/m squared - DWEC - These things reflect sunlight (30%): water vapor - clouds - dust particles - earth's surface






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






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






19. Like weighing oneself on the scale.






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






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






22. Radiation absorbed by atmospheric greenhouse gases?






23. 78% nitrogen - 28% oxygen - Greenhouse gases: Have a more complex molecular structure and can absorb and re:radiate heat in all directions.






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






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






26. 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.






27. Ice sheets have a very ____ Albedo






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






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

30. CO2 ____ in winter in the NH and ____ decreases during the 'greening season'






31. The amount of light reflected by an object.






32. 10 : 1 - grounding ; surface






33. 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






34. 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






35. Climate models suggest once the sea ice cover is thinned sufficiently - a strong kick from natural variability could initiate a rapid slide towards ice-free conditions in the summer.






36. Really measures volume.






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






38. 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:






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






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






41. Where do greenhouse gases warm up the Earth?






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






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






44. Laser radar - H V - Long time series - high accuracy - Density






45. Cooler water and drought conditions.






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






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






48. Wet gets _____ - dry gets ____ - Wet - 50ON (sub polar) Canada - N Europe - Russia - Tropical area- monsoon (rainforest) - Drier - Subtropics - Australia - S. Africa - Mediterranean - Caribbean - Mexico - SW US






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