Meteorologists are able to predict weather within probable ranges because air masses responsible for weather interact in predictable ways. the boundary at which two air masses meet is called a front, which is the main cause of stormy weather. this weather map shows conditions for severe weather. which statement best elaborates on how air masses would interact to cause severe weather? a) warm air masses and cold air masses have different densities, and when they mix, their densities stabilize, and excess moisture is released. b) as the fronts move away from one another, the cold air mass is heated by the warm air mass. when cool air becomes warm, precipitation falls. c) cold air is denser than warm air, so the cold air mass travels beneath the warm air, pushing it up. storms are often the result of rising warm air. d) since warm air is more dense than cold air, the cold air mass is forced higher. when the cold air becomes too heavy, it releases heavy precipitation.
