What term describes the boundary surface between two distinct air masses with different densities, temperatures, and humidities?

💡 Solution & Explanation

A meteorological front is the transition zone separating two distinct air masses possessing contrasting densities, temperatures, and moisture levels. Depending on the movement of these air masses, fronts are classified into cold, warm, stationary, and occluded types, often triggering significant weather changes and precipitation. Frontal activity is a dominant feature of mid-latitude weather systems and cyclogenesis.
