Question

Quizplus · Accepted Answer

When an occlusion occurs, a cold front catches up and overtakes a warm front. The warmer air is lifted from the surface because it is less dense than the colder air. This lifting of warm air results in the formation of clouds and precipitation. Therefore, the correct option is D where the cold front overtakes the warm front and the warmer air is lifted from the surface.
