Question

The boundary between cold and warm air masses is called a?...

Answer 1

Where air masses converge, they form boundaries called "fronts". 3-D view of a cold front. Fronts are identified by change of temperature based upon their motion. With a cold front, a colder air mass is replacing a warmer air mass. A warm front is the opposite affect in that warm air replaces cold air.

Step-by-step explanation:

Answer 2

With cold fronts and warm fronts, the air mass at the leading edge of the front gives the front its name. ... When two air masses meet together, the boundary between the two is called a weather front. At a front, the two air masses have different densities, based on temperature, and do not easily mix.
