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. ~10% of incident solar energy (albedo 90)






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

3. Same as heating an apartment v home - Thinner atmosphere than tropics; warms faster.






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






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






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






7. Warming- positive feedback - Cooling- negative feedback.






8. How often does El Nio occur?






9. Descending Air dry - Convection cells are wet.






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






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






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






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






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






15. Total absorbed solar radiation






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






17. Floating extensions are ice shelves - rivers of ice are ice streams or outlet glaciers - the junctions with the ocean are called the grounding line.






18. 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.






19. 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






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






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






22. The land-surface configuration that results from the melting of ground ice in a region where permafrost degrades is called Thermokarst.






23. 240 w/m squared






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






25. 85%






26. 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.






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






28. Amount of light absorbed by surface






29. 23 -45 degrees. The Larger the tilt the larger the variability of the seasons.

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






31. 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.






32. 1. Keeps the ocean and the earth cooler 2. Coastal impacts of ice: prevents waves from eroding coastlines and protects from storms. 3. Ecological importance of ice: a. Most visibly for the many fish - birds - and mammal species that live in - on - or






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






34. US is responsible for ___ of the total CO2






35. 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






36. Forms in a mosaic of favoured locations.






37. 20% human produced CO2 emissions. Tropical forests hold around 50% of the carbon present in vegetation on Earth.






38. Hydrological drought is associated with the effect of low rainfall on water levels in rivers -!reservoirs -!lakes and aquifers.






39. Water vapor - 36-70% - carbon dioxide - 9-26% - methane - 4-9% - ozone - 3-7%






40. High vs low






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






42. Low clouds are a ____ feedback; they will reflect more sunlight. Clouds reflect shortwave radiation but also absorb longwave radiation






43. 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






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






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






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






47. Arctic troposphere is thinner (8-10 km) than the tropics...The depth of the atmospheric layer is much shallower in the Arctic - It takes less energy to warm the Arctic rather than the Tropics - Same as heating an apartment vs. a house






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






49. 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.
