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. 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.






3. 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






4. 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






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






6. Like weighing oneself on the scale.






7. Measures input and output.






8. Extent 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.






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






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






11. Where do greenhouse gases warm up the Earth?






12. Ocean retains ____ CO2






13. 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






14. Is defined usually on the basis of the degree of dryness (in comparison to some 'normal' or average amount






15. Long time series started in the '70s and yielding good data in the '90s - Detects elevation with high accuracy: 10 cm precision (laser) to 1 m (radar) - 2/3 Gravity Surveys (GRACE) - Weighing the total mass every 30 days - Direct monthly estimate






16. The difference between the incoming radiation energy and the outgoing radiation energy - A measure of the net energy.






17. How often does El Nio occur?






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






19. 1.4 USA - 57 m total sea level equivalent






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






21. In ________- inversion layer is more common in the Arctic






22. 23 -45 degrees. The Larger the tilt the larger the variability of the seasons.

23. Greenhouse gases are a ___ portion of the atmosphere






24. LW - SW - 55% absorbed by surface






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






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






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






28. Greenhouse gases are mixed in the ____






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

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






31. The land-surface configuration that results from the melting of ground ice in a region where permafrost degrades is called Thermokarst.






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

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






34. 1. Altimetry survey 2. Time-variable gravity 3. Ice motion + Regional Climate Modeling






35. Volcanic eruptions - Sunspots - Wobbly Earth






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






37. Radiation absorbed by atmospheric greenhouse gases?






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. 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.






40. CO2 GHG forcing - H2O - dominant/major GHG






41. Cooler water and drought conditions.






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






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






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






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






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






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






48. Peru and Ecuador to the equatorial central pacific - Causes irregular warming in sea surface






49. Warming- positive feedback - Cooling- negative feedback.






50. Industry 40% - Buildings 31% - Transportations 22% - Agriculture 4%
