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. Frozen +2 years - Few centimeters to 1500 m






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






3. 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






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






5. 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.






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






7. Fresh snow and snow-covered sea ice may have an albedo higher than 80% - even when melting in the summer. Sea ice has a higher albedo and can absorb as little as 10% of the solar energy. On average - sea ice albedo is around 85%






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






9. 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






10. Reduction of snow and ice cover - Changes in atmospheric circulation.






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






12. 23 -45 degrees. The Larger the tilt the larger the variability of the seasons.

13. Trade winds blow from East to West - Pool of warm water in the west - Meanwhile deep colder water rises up in the Eastern Pacific - The sea level is ~ 50-60 cm higher in Western Pacific (Indonesia) than in the Eastern Pacific (South America/Peru) -






14. Really measures volume.






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






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






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






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






19. Over the Northern Hemisphere than the tropics.






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






21. Arctic warms faster than other parts of the globe in response to a given increase in greenhouse gasses - More direct route to warming - In the Arctic a greater fraction of any increase in radiation absorbed by the surface goes directly into warming t






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






23. Warming- positive feedback - Cooling- negative feedback.






24. 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






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






26. 20% human produced CO2 emissions. Tropical forests hold around 50% of the carbon present in vegetation on Earth.






27. 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






28. 342 W/m squared - DWEC - These things reflect sunlight (30%): water vapor - clouds - dust particles - earth's surface






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






30. 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.






31. 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






32. Poor resolution (200-400 km) does not allow us to distinguish glaciers and basins.






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






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






35. 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.






36. 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






37. ~15% of incident solar energy (albedo 85)






38. Carbon dioxide - Methane - Ozone - Water Vapor - Few others - Most ___________________ are mixed in the troposphere (Except water vapor) - Water vapor is concentrated closer to the ground.






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






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

41. In average: +1% in respect to 100 years ago.






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






43. Radiation that comes from the Sun - Visible light - 'near infrared' - ultraviolet radiation.






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






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






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






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






48. Amount of light absorbed by surface






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






50. O Unfrozen soil that stays within the permafrost.
