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






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






3. 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) -






4. Heat is provided by outside sources that flow down the continental slope to reach the deepest part of the glacier. High pressure decreases the melting point and favors melting.






5. 1.4 USA - 57 m total sea level equivalent






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






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






8. 342 W/m squared - DWEC - These things reflect sunlight (30%): water vapor - clouds - dust particles - earth's surface






9. 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






10. 20% human produced CO2 emissions. Tropical forests hold around 50% of the carbon present in vegetation on Earth.






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






12. By contrast reflects only about 7% of solar radiation (Albedo~7%) - absorbing 93%.






13. Measures input and output.






14. The amount of light reflected by an object.






15. 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






16. 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.






17. How much is the planet really warming?






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






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






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






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






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






23. High vs low






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






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






26. The Day After Tomorrow - Circulation will slow by 10% to 50% in the next century






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






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






29. 2ppm of the atmosphere - less than 20% of greenhouse gases - 1/3 greenhouse gases effect of CO2






30. 1. They are the largest contributor to sea level rise 2. Can affect the thermohaline circulation (mainly in Greenland) 3. Are directly connected to climate change






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






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






33. 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






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






35. Land Based Ecosystems retain ____ CO2.






36. Summer increase in cloud cover - Winter decrease in cloud cover.


37. 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.






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






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






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






41. 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






42. A thick - floating slab of freshwater ice extending from coast to coast.






43. They saw a massive thinning of the ice where it enters into the ocean - This is due to the pronounced melting of the ice once it is in contact with the ocean. Melt rates of 25 m/year near the grounding lines and more than 10 m/year on average.






44. By contrast reflects only about 7% of solar radiation (Albedo~7%) - absorbing 93%.






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






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






47. Greenhouse gases are a ___ portion of the atmosphere






48. Number of days that exceed a given temperature






49. On a clear cold day - the thin layer of air hugging the ground is called inversion. This layer is much cooler than the air a few hundred meters above it.






50. Antarctica - stratosphere - Sep-Oct
