Name ______________________FRONTS/AIR MASSESVersion 2Page 1croes1)Base your answer to the following question on the maps below and on your knowledge of Earth science. Themaps show a portion of India and Southeast Asia, bordering on the Indian Ocean, during the winter andsummer monsoon seasons. Large areas of high and low air pressure are shown during each season.1) cP2) mT3) cT4) mPWhich two-letter symbol represents the most likely air mass formed over portions of the Indian Oceanshown on the maps?1)2)3)4)2) Which cross section correctly represents a cold front and the air-mass movements associated with thisfront?1) mT2) mP3) cP4) cT3) Which type of air mass would most likely form over thePacific Ocean north of Aleutian Trench?1)source region where the air mass formed2)direction of Earth’s surface winds3)path the air mass follows along a land surface4)rate of Earth’s rotation4)The properties of an air mass are mostly determinedby the1)continental tropical2)maritime tropical3)maritime polar4)continental polar5)An Earth science student observed the followingweather conditions in Albany, New York, for 2 days:The first day was warm and humid with southerlywinds. The second day, the temperature was 15degrees cooler, the relative humidity had decreased,and wind direction was northwest. Which type of airmass most likely had moved into the area on thesecond day?

Version 2Page 3croes9)Base your answer to the following question on the cross section below and on your knowledge of Earthscience. The arrows on the cross section represent the air movement along a weather front between twodifferent air masses. The air masses are labeled.1)The cP air mass is warmer and less humid.2)The cP air mass is cooler and more humid.3)The mT air mass is warmer and more humid.4)The mT air mass is cooler and less humid.Which statement best describes the difference in air temperature and humidity between the cP and mTair masses?1)2)3)4)10)The three diagrams below represent three frontal boundaries with the surface locations of the frontslabeled A, B, and C. Arrows indicate direction of air movement.Which table correctly matches each letter with the type of frontal boundary it represents?
Version 2Page 4croesBase your answers to questions 11and 12on the weather map below and on your knowledge of Earthscience. The weather map shows a low pressure system over New York State on a July day. The Lrepresents the center of the low, and two fronts extend from this center. Locations of some cities areindicated.1)2)3)4)11)Which map shows the most probable areas of precipitation that would appear on a radar image taken atthe time of these frontal positions?1)Buffalo2)Elmira3)Plattsburgh4)New York City12)If the center of the low-pressure system follows a normal storm track, toward which city would thecenter of this low most likely move?
Version 2Page 5croes13)Base your answer to the following question on the map below and on your knowledge of Earth science. Themap shows typical weather systems over North America. Letters X,Y,and Z represent locations on themap. The isobars on the map are measured in millibars (mb).1)occluded front2)stationary front3)warm front4)cold frontWhich type of front extends northwest from location Y?1) occluded2) stationary3) cold4) warm14) The weather map below shows a portion of a low-pressure system.Which front will most likely pass over location A during the next two hours'?
Version 2Page 6croesBase your answers to questions 15and 16on the weather map below and on your knowledge of Earthscience. The map of a portion of eastern North America shows a high-pressure center (H) and alow-pressure center (L), frontal boundaries, and present weather conditions.1)Canada2)Pacific Ocean3)New York State4)Gulf of Mexico15) What was the most likely source region for the air mass over Pennsylvania?1) haze2) snow3) thunderstorms4) fog16) Which weather condition is shown along the cold front?
