Quizplus · Accepted Answer

The boundary between two different air masses is called a front. The other answer choices are not correct. The Southern Oscillation refers to atmospheric changes in the Pacific Ocean and is not related to air masses. The windward side refers to the side of a mountain range that faces the direction from which the wind is blowing. A pressure gradient refers to the rate at which air pressure changes in a given area.
