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






2. 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.






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






4. O Unfrozen soil that stays within the permafrost.






5. 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






6. 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%






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






8. How much is the planet really warming?






9. Ocean retains ____ CO2






10. Sea ice - Glaciers and Ice sheets - Alaska- ice glaciers - Greenland- ice sheets






11. 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.






12. SALTY WATER = MORE DENSE - Maximum density at 4OC - This is why ice melting is a big deal; if the whole circle slows down - Ice bergs are fresh water higher sea level rise.






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






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






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






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






17. Over the Northern Hemisphere than the tropics.






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






19. The air can hold less water vapor - Consequently - less water can be evaporated in the air - and only a small portion of energy is used in this process - Most of the energy that reaches the Arctic goes directly into warming the air






20. 2ppm of the atmosphere - less than 20% of greenhouse gases - 1/3 greenhouse gases effect of CO2






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






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






23. Cooler water and drought conditions.






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






25. Atmospheric Cooling - Both negative (stabilizing) feedbacks - It is not happening now - but it has happened in the past - Ice-albedo feedback was the dominant feedback during the ice ages.






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






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. Number of days that exceed a given temperature






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. 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.






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






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. Permafrost- A frozen soil






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






35. More common






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






37. Forms in a mosaic of favoured locations.






38. Temperature needed to melt at depth is much lower than that needed to melt at the surface.






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






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






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






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






43. If the mean annual air temperature is only slightly below 0 degrees C - permafrost will form only in spots that are sheltered.






44. Where do greenhouse gases warm up the Earth?






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






46. 1.4 USA - 57 m total sea level equivalent






47. LW - SW - 55% absorbed by surface






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






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






50. 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
