Which type of front forms when a cold front overtakes and forces a warm front upwards?
AI Explanation
The correct answer is B) An occluded front.
When a cold front overtakes and forces a warm front upwards, the result is the formation of an occluded front. In this scenario, the cold front catches up to the warm front, and the colder air mass from the cold front undercuts the warm air mass, forcing the warm air to rise. This creates an occluded front, where the cold front and warm front merge, with the colder air mass displacing the warmer air mass.
The other options are incorrect because: A) A warm front is formed when warmer air rises over colder air, B) A cold front is formed when colder air displaces warmer air, and D) A stationary front occurs when a warm front and cold front meet but neither advances.
