Quizplus · Accepted Answer

Advection fog forms when warm, moist air moves over a cooler surface, causing the air to cool to its dew point and condense into fog. Along the Pacific coast, the surface water near the coast is much colder than the water farther offshore, often due to upwelling, which brings cold water from the deep ocean to the surface. This temperature difference is what causes advection fog to form.
