Which type of fog often occurs in coastal areas where warm moist air meets cooler land?

Advection fog is formed when warm, moist air moves over a cooler surface, causing the air to cool and condense into fog. This phenomenon often occurs in coastal areas, where warm, humid air from the ocean travels over cooler land or water, leading to condensation. As this warm air moves horizontally across the cooler terrain, it can significantly lower its temperature to the dew point, resulting in the formation of fog.

In contrast, radiation fog typically develops on clear, calm nights when the land loses heat through radiation, cooling the air near the surface. Ice fog is found in very cold conditions, primarily in polar regions, when water vapor freezes into tiny ice crystals suspended in the air. Steam fog occurs when cold air moves over warmer water, causing moisture to evaporate and then condense rapidly into fog.

Understanding these different types of fog helps to recognize atmospheric conditions specific to each, particularly in relation to their formation processes.
