Quizplus · Accepted Answer

This statement is true. When a cold front overtakes a warm front in a wave cyclone, it forms an occluded front, which is a boundary of cooler air that has surrounded a mass of warm air. This occurs as the low-pressure center of the cyclone moves towards an area of cooler air, causing the cold front to overtake the warm front.
