• 1. A) always lessB) always greaterC) always the sameD) sometimes less and sometimes greater1. Compared to the density of liquid water, the density ofan ice cube isA) 1,000.0 mb B) 1,005.5 mbC) 1,013.2 mb D) 1,020.4 mb2. When the height of the mercury in a barometer is 29.92inches, the barometric pressure isA) dewpoint B) wind speedC) air pressure D) visibility3. Which weather variable is measured by a barometer?
• 2. 4. Base your answer to the following question on the data table, which shows recorded information for a majorAtlantic hurricane and the map below.Identify the weather instrument used to measure the air pressure associated with this hurricane.
• 3. 5. Base your answer to the following question on the weather map below, which shows a low-pressure systemover the eastern United States. Letters A through D represent weather stations.A) barometer B) thermometer C) psychrometer D) anemometerWhich weather instrument was used to measure wind speed at station D?6. Base your answer to the following question on the weather map provided below, which shows surfaceair-pressure readings, in millibars, at various locations in the United States and Canada. The 1020-millibarisobars have been drawn and labeled.What weather instrument was most likely used to measure these air pressures?
• 4. 7. What is the air pressure indicated by the diagram of themercury barometer at the right?A) 1028.1 mb B) 1028.5 mbC) 1029.5 mb D) 1031.0 mb8. Base your answer to the following question on Thediagram below represents an aneroid barometer thatshows the air pressure, in inches of mercury.A) 1009.0 mb B) 1012.5 mbC) 1015.5 mb D) 1029.9 mbWhen converted to millibars, this air pressure is equal to9. Base your answer to the following question on theweather map below. Points A, B, C, and D are locationson Earths surface.A) A B) B C) C D) DThe strongest winds are closest to locationA) air density due to unequal heating of Earth’ssurfaceB) ocean wave heights during the tidal cycleC) rotational speeds of Earth’s surface at variouslatitudesD) distances from the Sun during the year10. Surface winds on Earth are primarily caused bydifferences in
• 5. 11. Base your answer to the following question on theweather map below, which shows a low-pressuresystem centered near Poughkeepsie, New York. Isobarsshown are measured in millibars.A) Danbury toward New York CityB) Poughkeepsie toward ScrantonC) Binghamton toward DanburyD) Port Jervis toward BinghamtonSurface winds are most likely blowing fromA) air temperature toward regions of lower airtemperatureB) air pressure toward regions of lower air pressureC) latitudes toward regions of lower latitudesD) elevations toward regions of lower elevations12. Earth’s surface winds generally blow from regions ofhigherA) high air temperature to regions of low airtemperatureB) high air pressure to regions of low air pressureC) high precipitation to regions of low precipitationD) convergence to regions of divergence13. Winds blow from regions ofA) humidity differencesB) air pressure differencesC) the revolution of EarthD) the rotation of Earth14. What is the primary cause of winds?A) -17°C B) 6°C C) 3°C D) 4°C15. What is the dewpoint temperature when the dry-bulbtemperature is 14°C and the wet-bulb temperature is10°C?A) 1ºC B) -2ºC C) -5ºC D) 4ºC16. What is the dewpoint temperature when the dry-bulbtemperature is 12ºC and the wet-bulb temperature is7ºC?A) 6ºC B) 12ºC C) 14ºC D) 17ºC17. What is the approximate dewpoint temperature whenthe dry-bulb temperature is 24ºC and the wet-bulbtemperature is 18ºC?A) 1º C B) -10º CC) 7º C D) 4º C18. What is the approximate dewpoint temperature if thedry-bulb temperature is 18ºC and the wet-bulbtemperature is 11ºC?A) 1ºC B) -5ºC C) 6ºC D) 4ºC19.
