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. Volcanic eruptions - Sunspots - Wobbly Earth






2. 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.






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






4. High vs low






5. 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






6. 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






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






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






9. 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.






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






11. Over the Northern Hemisphere than the tropics.






12. Sea ice extent in Antarctica is rapidly reducing. Seasonal variability. People - Animals and Ice






13. 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






14. Warming- positive feedback - Cooling- negative feedback.






15. High clouds are a ____ feedback; larger greenhouse warming - Clouds reflect shortwave radiation but also absorb longwave radiation






16. Pollution: heat and sunlight cook the air and the chemical compounds which are in it. This combines with the nitrogen oxide and creates 'smog'. This makes breathing difficult for those with respiratory ailments.






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






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






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






20. 240 w/m squared






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






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






23. 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






24. 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






25. 85%






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






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






28. 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






29. Holds unique and key information - Are highly interconnected - Respond and drive climate change - Are the largest freshwater reservoirs of the planet - Ice cores tell us that in climate records - nothing is regular and ice sheet plays major role.






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






31. Descending Air dry - Convection cells are wet.






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






33. 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.






34. Where does the ozone protect us?






35. 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.






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






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






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






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






40. 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






41. Land Based Ecosystems retain ____ CO2.






42. Taliks are found under lakes because of the ability of water to store and vertically transfer heat energy - Vertical extent of the taliks found under lakes is related to the depth and volume of the overlying water body.






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






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






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






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






47. InSAR - +snow/-ice loss - ice dynamics - requires a lot of data.






48. 10 : 1 - grounding ; surface






49. 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.






50. 2ppm of the atmosphere - less than 20% of greenhouse gases - 1/3 greenhouse gases effect of CO2
