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. Atmosphere retains ____ CO2






2. Longwave radiation - any radiation with a long wave will heat up quickly.






3. 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






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






5. 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:






6. 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






7. 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






8. 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.






9. The Earth emits this.






10. Less frequent and weaker






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






12. High vs low






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






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






15. 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.






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






17. 1.4 USA - 57 m total sea level equivalent






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






19. 85%






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






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






22. Cooler water and drought conditions.






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






24. If the Earth is warmer - are we going to have the Hadley cell stronger or weaker? Hotter = heat rises which increases the circulation.






25. Amount of light absorbed by atmosphere






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






27. 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.






28. ~10% of incident solar energy (albedo 90)






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






30. The last portion of a glacier grounded to bedrock - after this line there are ice shelves.






31. Radiation absorbed by atmospheric greenhouse gases?






32. Permafrost- A frozen soil






33. The warmer the temperature - the deeper the active layer - thaws and refreezes every year - Permafrost below freezing for two or more years.






34. 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.






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






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






37. 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.






38. 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.






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






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






41. Antarctica - stratosphere - Sep-Oct






42. Soil at or below the freezing point of water for two or more years - Can be: Terrestrial - Subsea - Can be: Continuous: exists across a landscape as an unbroken layer. More than 90% is frozen - Discontinuous






43. Melting Point decreases






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






45. Some parts of the planet are dry because of their location: most of the deserts are around 30 N and 30 S - where sinking air predominates






46. 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






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






48. 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.






49. Betts et al found that: if CO-2 __________ this has a physiological effect on plant transpiration increased simulated runoff by 6% b. How? i. More CO2 1. Plants pores open less 2. This reduces transpiration 3. More water in the land surface






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