Question

How is an occluded front different from a cold front?

Warm air is pushed up during an occluded front, while cold air moves quickly during a cold front.
Occluded fronts cause warm air to feel dry, while cold fronts cause ground temperatures to feel cooler.
Warm air moves slowly during an occluded front, while cold air is cut off from the ground in a cold front.
Occluded fronts cause rapid changes in weather conditions, while cold fronts cause widespread cloud formation

Answer 1

The best choice is the first one: "Warm air is pushed up during an occluded front, while cold air moves quickly during a cold front."

Explanation/nuance:
- An occluded front forms when a faster-moving cold front catches up to a preceding warm front and lifts the warm air completely off the ground. So the warm air is pushed upward (cut off from the surface) between two cooler air masses.
- A cold front is the leading edge of a colder air mass advancing into warmer air. The cold air wedges under the warm air and often moves relatively quickly, forcing the warm air up steeply and producing a band of clouds and often showers or thunderstorms and a rapid temperature drop after passage.

(So both fronts lift warm air, but in an occlusion the warm air is removed from the surface by the overtaking front; in a cold front the cold air is the active, fast-moving feature along the surface.)
