MET 1010 FINAL EXAM STUDY GUIDETest 1 Answers:1. In the thermosphere, the temperature can exceed 1800 degrees F, yet a person’s exposed hand might not feel hot primarily becausea. The density of the atmosphere is low, so fewer molecules would collide with a persons hand2. In the very early stage of the earth’s formation, the earths atmosphere was composed chiefly of the gasesa. Hydrogen and helium3. SKIP4. An atmospheric gas whose concentration near the earth’s surface varies significantly from one location to another isa. Water vapor5. Which latitude listed below would experience the fewest hours of daylight on December22?a. 60 degrees north6. Water vapor isa. An invisible gas7. Most weather is confined to that subdivision of the atmosphere known as thea. Troposphere8. When it is January and winter in the N. Hemisphere, it is (blank) and (Blank) in the S. Hemispherea. January and Summer9. Convection takes place ina. Liquids or gases10. In the equal volumes, cold air is (blank) warm aira. More dense than11. Which of the following energy transfer process can take place in a vacuuma. Radiation12. In response to the same input of heat, which one of the following substances exhibits the smallest rise in temperaturea. Increased by 2 degrees celcius13. One thousand calories of heat are added to 500 grams of liquid water. The temperature of the water a. Increased by 2 degrees celcius14. During the course of the year the sun will first disappear from the view for the entire day at the south pole on what datea. March 2115. The ultimate source of solar radiation isa. Nuclear fission16. According to Wien displacement law, which one of the following objects emits the shortest electromagnetic wavea. The sun17. The earths surface and atmosphere predominantly emit what type of radiationa. Infrared18. At night, air temperature tends to be lower when the sky isa. Clear19. At 0 degrees C (32 degrees F) the heat of vaporization of water is abouta. 600 calories per gram20. The fraction of the sun’s energy absorbed by the earth’s surface is approximately a. 50 %21. The term ‘Meteorology’ actually dates back to a. The time of Aristotle22. Frozen clothes hanging on a line in subfreezing weather ‘dry’ by a process calleda. Sublimation23. Suppose two identical air columns have the same temperature and the same number of air molecules inside. If one column is saturated with water vapor and the other is completely dry, then the air is greatest ina. The dry columns24. When water changes from a liquid to a vapor, we call this processa. Evaporation25. The layer of the atmosphere which is characterized by inversion everywherea. Stratosphere26. The albedo of the moon is 7% this means thata. 7% of the sunlight that strikes the moon is reflected27. If the average temperature of the sun increased, the wavelength of maximum solar emission woulda. Shift to a shorter wavelength28. Heat transferred upward from the surface of the moon can take place by a. Radiation29. During the summer in the N. Hemisphere the length of the day (blank) the length of the nighta. Is longer than30. We have seasons becausea. The earth’s axis of orbit is tilted with respect to the plane of its orbit31. Low clouds retard (slow down/reduce) surface cooling at night better than skies becausea. The clouds absorb and radiate infrared energy back to earth32. If very cold air is brought indoors and warmed with no change in its moisture content, the relative humidity of this air willa. Decrease33. The cooling of the ground to produce dew is mainly the result ofa. Radiational cooling34. Relative humidity isa. The ratio of the amt of water vapor in the air to what the air can hold times 100%35. The equilibrium vapor pressure over an ice crystal is (blank) the equilibrium vapor pressure over a cloud dropa. Less than36. The order of the layers of atmosphere from lowest to highest area. Troposphere, stratosphere, mesosphere, thermosphere37. How many calories are required to change two grams of ice at 0 degrees C to vapor at 30 degrees Ca. None of the above38. Skip39. How does blue and red light differ?a. The wavelength of red light is longer40. When the relative humidity is 100%a. The vapor pressure equals the saturation vapor pressure and the air has as muchmoisture in it as it can hold41. What time of the day is relative humidity the highest?a. Just before dawn42. Relative humidity can be defined asa. The amt of moisture in the air divided by the amt of moisture the air can hold times 100% and the actual vapor pressure divided by the saturation vapor pressure times 100%43. If you add 82 calories to 2 grams of ice that is -2 degrees C, you end up with a. 1 gram of ice at 0 degrees and 1 gram of water at 0 degrees44. Sunsets appear red becausea. On the way through the atmosphere, all the shorter wavelengths are scattered out of the beam45. The sky is blue becausea. Of the electrical size of air molecules make it such that the scattering is describedas Rayleigh scattering after Lord Raleigh who determined that when the electrical size was very small that the shorter the wavelength would scatter more, and that the degree of scattering should be described as proportional to 1 over the wavelength to the 4th power46. Equilibrium isa. A state where there is no net change in status quo. For example: it equals out47. A radar can tell youa. How hard it is raining and where a storm is moving48. Skip49. A layer of the atmosphere where the molecules are sorted by their mass with the heaviest on the bottom is called thea. Heterosphere 50. Electrical size isa. The ratio of the scatterer’s circumference to wavelength of the illuminating radiationTest 2 Answers:1-8 are cloud identification9. The cloud with the greatest vertical growth is:a. Cumulonimbus10. Which cloud is least likely to produce precipitation that reaches the ground?a. Cirrocumulus11. Detatched clouds of delicate, “wispy”, and fibrous appearance without shading, usually white in color and sometimes of a silky appearancea. Cirrus12. Secondary rainbows occur when:a. two internal reflections of light occur in rainbows13. The color that is refracted the most as sunlight enters a raindrop is:a. blue14. Clouds in the tropics tend to move from east to west, consequently, which rhyme best describes a rainbow seen in the tropics?a. Rainbow in at the break of dawn, rain is surely gone15. Halos are caused bya. Refraction of light through ice crystals16. The blue of the sky is
