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. Number of days that exceed a given temperature






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






3. Descending Air dry - Convection cells are wet.






4. Amount of light absorbed by surface






5. Warming- positive feedback - Cooling- negative feedback.






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






7. Clouds 40~90% - Vegetation 10~15%






8. 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






9. Greenhouse gases are a ___ portion of the atmosphere






10. 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






11. 2ppm of the atmosphere - less than 20% of greenhouse gases - 1/3 greenhouse gases effect of CO2






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

13. Forms in a mosaic of favoured locations.






14. 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






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






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






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






18. Surface Mass Balance is of the order of _____ melting is ____ times more.






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






20. 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.






21. 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






22. A climate forcing agent formed through the incomplete combustion of fossil fuels - biofuel - and biomass; emitted both anthropogenic:ally and naturally.






23. 240 w/m squared






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






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






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






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






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






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






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






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






32. Less frequent and weaker






33. Heat is provided by outside sources that flow down the continental slope to reach the deepest part of the glacier. High pressure decreases the melting point and favors melting.






34. 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






35. Land Based Ecosystems retain ____ CO2.






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






37. How much is the planet really warming?






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






39. 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) -






40. Set up in 1988 by WMO and UNEP.






41. Volcanic eruptions - Sunspots - Wobbly Earth






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






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






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






45. 85%






46. US is responsible for ___ of the total CO2






47. O The amount of energy moving in the form of photons or other elementary particles at a certain distance from the source per unit of area per second. Area/second






48. Top layer of soil that thaws during the summer and freezes again during autumn. - Between 1 and 3 m thick.






49. Antarctica - stratosphere - Sep-Oct






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