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






2. Less frequent and weaker






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






4. Amount of light absorbed by surface






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






6. Radiation absorbed by atmospheric greenhouse gases?






7. ~10% of incident solar energy (albedo 90)






8. 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






9. 240 w/m squared






10. Industrial product - 300 ppb (parts per billion)






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






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






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






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






15. Where do greenhouse gases warm up the Earth?






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






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






18. The Earth emits this.






19. Forms in a mosaic of favoured locations.






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






21. At the bottom of the ice sheets the temperature doesn't necessarily have to be above 0... it could _____ more easily because of the water






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






23. 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






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






25. Total absorbed solar radiation






26. 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.






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






28. A process whereby slabs of ice at the glacier margin mechanically fracture and detach from the main ice mass -






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






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






31. Hydrological drought is associated with the effect of low rainfall on water levels in rivers -!reservoirs -!lakes and aquifers.






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






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






34. LW - SW - 55% absorbed by surface






35. 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






36. An area of unfrozen ground that is open to the ground surface but otherwise enclosed in permafrost.






37. Really measures volume.






38. 20% human produced CO2 emissions. Tropical forests hold around 50% of the carbon present in vegetation on Earth.






39. Clouds 40~90% - Vegetation 10~15%






40. 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!






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






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

44. Is not an externally imposed perturbation to the climate system.






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






46. Warming- positive feedback - Cooling- negative feedback.






47. 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.






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






49. 342 W/m squared - DWEC - These things reflect sunlight (30%): water vapor - clouds - dust particles - earth's surface






50. 2ppm of the atmosphere - less than 20% of greenhouse gases - 1/3 greenhouse gases effect of CO2
