what must occur for air masses to form fronts?\nthey must increase in strength.\nthey must collide with each other.\nthey must move from west to east.\nthey must create air - pressure differences.
Answer
Brief Explanations:
A front is formed when two different air - masses meet or collide. Changes in strength, direction of movement (west - to - east), or creating air - pressure differences are not the defining factors for front formation.
Answer:
They must collide with each other.
