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. 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.






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






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






4. In _______ - the inversions are less frequent and weaker in the Arctic.






5. Land Based Ecosystems retain ____ CO2.






6. Volcanic eruptions - Sunspots - Wobbly Earth






7. Permafrost- A frozen soil






8. 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.






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






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






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






12. Amount of light absorbed by surface






13. If the Earth is warmer - are we going to have the Hadley cell stronger or weaker? Hotter = heat rises which increases the circulation.






14. Radiation absorbed by atmospheric greenhouse gases?






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






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






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






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






19. Atmosphere retains ____ CO2






20. Where do greenhouse gases warm up the Earth?






21. 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.






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






23. The Earth emits this.






24. How often does El Nio occur?






25. 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






26. Cooler water and drought conditions.






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






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






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






30. 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






31. Ice sheets have a very ____ Albedo






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






33. 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.






34. 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.






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






36. 1.4 USA - 57 m total sea level equivalent






37. High vs low






38. 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






39. The buoyant force is equal to the weight of the displaced water.

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






41. The depletion of stratospheric ozone layer in Antarctica in Springtime (august through October)






42. Under higher pressure the melting point decreases ____ - The pressure comes from the weight of the ice shelf.






43. Nitrogen (N2 78%) and Oxygen (O2 21%) - Their linear 2 atom molecular structure






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






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






46. Grace - Tells us how much mass change we have - M - This is the measure of gravity (gives us the mass) - Directly measure mass change - Poor resolution






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






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






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






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