Question

Quizplus · Accepted Answer

A front is a boundary between two air masses that have different temperatures, humidities, and wind directions. As a result, when a front passes through an area, there are often abrupt changes in temperature, humidity, and wind direction. Therefore, option D, abrupt changes in temperature, humidity, and wind direction, is the most accurate description of a front on a synoptic weather chart.
