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






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






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






4. Greenhouse gases are mixed in the ____






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






6. Ice melting rapidly? What type causes sea level to rise? What have been the main contributors to sea level rise so far? What are the impacts of melting ice? - On nature - On humans






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






8. LW - SW - 55% absorbed by surface






9. Like weighing oneself on the scale.






10. Melting Point decreases






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






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






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. Concentration of 380 ppmv - Have risen about 40% - Preindustrial~ 270~280 ppmv






15. Radiation absorbed by atmospheric greenhouse gases?






16. Number of days that exceed a given temperature






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






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






19. 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






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






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

22. Antarctica - stratosphere - Sep-Oct






23. 85%






24. 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.






25. 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






26. Amount of light absorbed by surface






27. Over the Northern Hemisphere than the tropics.






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






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






30. 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






31. Arctic troposphere is thinner (8-10 km) than the tropics...The depth of the atmospheric layer is much shallower in the Arctic - It takes less energy to warm the Arctic rather than the Tropics - Same as heating an apartment vs. a house






32. Occurs when there is not enough water available for a particular crop to grow at a particular time.Typically seen after!meteorological drought (when rainfall decreases) but before a hydrological drought






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






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






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






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






37. Just remember the general direction of the circulation - Rising northern pacific. You start in between Greenland and Europe (youngest water) - Oldest water is in the Pacific Ocean - Salty water> fresh water - Cold Water > Warm Water






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. Absolute thresholds - Monthly maximums and minimums - Threshold departures - Percentile departure - Atmospheric Water Vapor: More water vapor in the air - warmer nights!






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






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






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






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






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






45. 1. Land usage changes 2. Seasonal timing 3. Rising CO2 levels may be a factor






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






47. Is best viewed as a combination of...- Natural Variability - Associated with atmospheric circulation patterns - Growing Radiative Forcing - Associated with rising concentrations of atmospheric greenhouse gases - Strongly suggests a human influence.






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






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

50. All processes that add snow or ice to a glacier or to flowing ice or snow cover.
