A good air mass source region is generally flat and of uniform composition with light surface
winds. correct answers True
On a weather map, the transition zone between two air masses with sharply contrasting
properties is marked by ____. correct answers a front
A situation, where a cold front overtakes a slower moving warm front, then underrides and lifts
off the ground both the warm front and the warm air mass, is called ____. correct answers cold
occluded front
