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. Radiation absorbed by atmospheric greenhouse gases?






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






3. The Earth emits this.






4. Frozen +2 years - Few centimeters to 1500 m






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






6. Same amount of H2O - Mass does not change - Density of ice < density of water - Volume of ice > volume of water






7. Is best viewed as a combination of...- Natural Variability - Associated with atmospheric circulation patterns - Growing Radiative Forcing - Associated with rising concentrations of atmospheric greenhouse gases - Strongly suggests a human influence.






8. Higher temperature increases atmospheric water vapor @ global scale more water vapor in the air that causes nights to stay warmer.






9. An area of unfrozen ground that is open to the ground surface but otherwise enclosed in permafrost.






10. Volcanic eruptions - Sunspots - Wobbly Earth






11. 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






12. 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.






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






14. ~10% of incident solar energy (albedo 90)






15. The transition of a substance from the solid phase directly to the vapor phase - or vice versa - without passing through an intermediate liquid phase.






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






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






18. Ice sheets have a very ____ Albedo






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






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






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






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






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






25. 10 : 1 - grounding ; surface






26. Changes in the Earth's solar radiation levels can impact the climate. Shortterm warming cycles on Earth.






27. 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






28. Over the past century what has happened to the Earth's temperature?






29. 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






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






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






32. Land Based Ecosystems retain ____ CO2.






33. 1.4 USA - 57 m total sea level equivalent






34. 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






35. 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.






36. 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) -






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






38. Mass balance due to processes that affect the surface of the ice sheet. Precipitation-evapotranspiration-runoff-blowing snow etc...






39. Like weighing oneself on the scale.






40. Closed talik can develop when lakes fill in with sediment and become deposits of dead plant material (bog).






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






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






43. 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.






44. Amount of light absorbed by atmosphere






45. Radiation that comes from the Sun - Visible light - 'near infrared' - ultraviolet radiation.






46. 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






47. 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.






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






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






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