Question 1234Navigation General

The correct answer is C) warm front at night. Fog is most commonly associated with a warm front at night. As a warm front approaches, the warmer, moist air mass overrides the cooler air near the surface, causing condensation and the formation of fog. This is especially common at night when the ground cools and the temperature difference between the warm and cool air masses is greatest. The other answer choices are incorrect because: A) Anticyclones, or areas of high pressure, are typically associated with clear skies and the dissipation of fog. B) Low pressure areas are more commonly associated with the formation of clouds and precipitation, not necessarily fog. D) Cold fronts in the spring can lead to the formation of fog, but this is less common than the warm front scenario described in the correct answer.
