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






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






3. 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.






4. 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!






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






6. 240 w/m squared






7. 20% human produced CO2 emissions. Tropical forests hold around 50% of the carbon present in vegetation on Earth.






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






9. 1.4 USA - 57 m total sea level equivalent






10. Total absorbed solar radiation






11. A mass of land ice - continental or sub-continental in extent - and thick enough to cover most of the underlying bedrock topography - If you have a warm ocean - it will melt the ice sheet. Its shape is mainly determined by the dynamics of its outward






12. The Earth emits this.






13. Ozone layer in high stratosphere (25-40 km altitude) absorbs about 95-99% of ultraviolet radiation.






14. Ice sheets have a very ____ Albedo






15. Is unfrozen ground that is exposed to the ground surface and to a larger mass of unfrozen ground beneath it.






16. Cooler water and drought conditions.






17. 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.






18. 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






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






20. How often does El Nio occur?






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






22. O Climate change in the Arctic is occurring now - Changes have been huge already






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






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






25. LW - SW - 55% absorbed by surface






26. Grace - Tells us how much mass change we have - M - This is the measure of gravity (gives us the mass) - Directly measure mass change - Poor resolution






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






28. Low clouds are a ____ feedback; they will reflect more sunlight. Clouds reflect shortwave radiation but also absorb longwave radiation






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






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






31. 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.






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






33. Water vapor means more water up in the clouds and less in the ground!






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






35. 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.






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






37. 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.






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






39. This is the total mass change - difference between input and outputs—snow accumulation-ablation.






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






41. Number of days that exceed a given temperature






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






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






44. What can cause a change in the Earth's climate balance?






45. 85%






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






47. More common






48. Land Based Ecosystems retain ____ CO2.






49. 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






50. CO2 - CH4 - O3 - H2O - N2O - CFCs
