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. 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.






2. The amount of light reflected by an object.






3. 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






4. The heat input is either driven by the 1- thermohaline circulation associated with sea ice formation. The direct influx of intermediate warmth water.






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






6. 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.






7. Is not an externally imposed perturbation to the climate system.






8. Land Based Ecosystems retain ____ CO2.






9. 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.






10. Amount of light absorbed by surface






11. 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






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






13. A naturally or artificially caused decrease in the thickness and/or areal extent of permafrost - It is caused by the deepening fo the active layer and the thawing of the adjacent permafrost.






14. How often does El Nio occur?






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






16. ~15% of incident solar energy (albedo 85)






17. 1.4 USA - 57 m total sea level equivalent






18. 2ppm of the atmosphere - less than 20% of greenhouse gases - 1/3 greenhouse gases effect of CO2






19. Sea ice - Continental ice sheets - Permafrost (frozen soil) - Mountain glaciers - Snow cover






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






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






22. 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






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






24. Extent 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.






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






26. Set up in 1988 by WMO and UNEP.






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






28. Like weighing oneself on the scale.






29. 342 W/m squared - DWEC - These things reflect sunlight (30%): water vapor - clouds - dust particles - earth's surface






30. Greenhouse gases are a ___ portion of the atmosphere






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






32. Where do greenhouse gases warm up the Earth?






33. 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.






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






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






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






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






38. 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.






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






40. 85%






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






42. Arctic warms faster than other parts of the globe in response to a given increase in greenhouse gasses - More direct route to warming - In the Arctic a greater fraction of any increase in radiation absorbed by the surface goes directly into warming t






43. The past climate...for this reason - both keep good records of climate change.






44. 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






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






46. 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.






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






48. US is responsible for ___ of the total CO2






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






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