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. Measures input and output.






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






3. 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






4. Concentration of 380 ppmv - Have risen about 40% - Preindustrial~ 270~280 ppmv






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






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






7. A dome shaped cover of perennial ice and snow.






8. 1. Land usage changes 2. Seasonal timing 3. Rising CO2 levels may be a factor






9. The amount of light reflected by an object.






10. The high pressure decreases the melting point and favors melting - Melt water being less dense rises along the water column along the ice shelf bottom and may either escape the cavity or refreeze at some intermediate depth. Melting point decreases:






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






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






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






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






15. 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.






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






17. Number of days that exceed a given temperature






18. 20% human produced CO2 emissions. Tropical forests hold around 50% of the carbon present in vegetation on Earth.






19. 23 -45 degrees. The Larger the tilt the larger the variability of the seasons.

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






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






22. How much is the planet really warming?






23. Precipitation intensity will rise ___ for every 1 OC of warming.






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






25. A mass of land ice - continental or sub-continental in extent - and thick enough to cover most of the underlying bedrock topography - If you have a warm ocean - it will melt the ice sheet. Its shape is mainly determined by the dynamics of its outward






26. Permafrost- A frozen soil






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. Warming- positive feedback - Cooling- negative feedback.






29. Soil at or below the freezing point of water for two or more years - Can be: Terrestrial - Subsea - Can be: Continuous: exists across a landscape as an unbroken layer. More than 90% is frozen - Discontinuous






30. Is defined usually on the basis of the degree of dryness (in comparison to some 'normal' or average amount






31. O Unfrozen soil that stays within the permafrost.






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






33. Clouds 40~90% - Vegetation 10~15%






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






35. The Earth emits this.






36. High clouds are a ____ feedback; larger greenhouse warming - Clouds reflect shortwave radiation but also absorb longwave radiation






37. ~10% of incident solar energy (albedo 90)






38. 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.






39. 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






40. The air can hold less water vapor - Consequently - less water can be evaporated in the air - and only a small portion of energy is used in this process - Most of the energy that reaches the Arctic goes directly into warming the air






41. Ocean retains ____ CO2






42. Total absorbed solar radiation






43. 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.






44. Number of days that land among the hottest of all days in that month's long-term record.






45. x7 smaller - 7m total sea level equivalent.






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






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






48. 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.






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






50. Long time series started in the '70s and yielding good data in the '90s - Detects elevation with high accuracy: 10 cm precision (laser) to 1 m (radar) - 2/3 Gravity Surveys (GRACE) - Weighing the total mass every 30 days - Direct monthly estimate
