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






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






3. 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






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






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






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






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






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






9. 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






10. Atmosphere retains ____ CO2






11. How much is the planet really warming?






12. Antarctica - stratosphere - Sep-Oct






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






14. 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






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






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






17. 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.






18. Precipitation extremes appear to generally increase across the planet at especially high latitudes.






19. Permafrost- A frozen soil






20. South polar vortex - Temperatures drop below 80O Celsius in the lower stratosphere - At these temperatures the chemicals in the stratosphere freeze and form Polar Stratospheric Clouds (PSCS) - These increase the concentration of CFCs in turn destroyi






21. Grounding line is the last portion of a glacier grounded to bedrock - after this line there are ice shelves - Glaciers contribute to sea level rise after passing the grounding line - Maximum thinning at grounding line.






22. 1. We live in troposphere. Greenhouse gases here warm up the Earth 2. Above stratosphere. The ozone in this layer protects us.






23. 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






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






25. Over the Northern Hemisphere than the tropics.






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






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






28. Refers to a body of freshwater - usually shallow - formed in a depression by melt water from thawing permafrost.






29. Thawing permafrost weakens coastal lands. Risk of flooding in coastal wetlands. Pollution and toxins locked in the snow and ice will be released.






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






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






32. The large-scale ocean circulation that moves water between the deep and surface ocean which effects salinity and temperature change - Supplies heat to the polar-regions.






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






34. Number of days that land among the hottest of all days in that month's long-term record.






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






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






37. Frozen +2 years - Few centimeters to 1500 m






38. 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






39. Higher temperature increases atmospheric water vapor @ global scale more water vapor in the air that causes nights to stay warmer.






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






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






42. 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






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






44. More common






45. A dome shaped cover of perennial ice and snow.
