What type of fog is formed when moist air is carried by wind up a mountain until cooled?

Upslope fog occurs when moist air is forced to ascend a slope, such as a mountain, due to wind. As the air rises, it expands and cools, leading to condensation of water vapor and the formation of fog. This process is typical in mountainous regions where terrain influences weather patterns. In contrast, advection fog forms when warm, moist air moves over a cooler surface and is cooled from below. Radiation fog develops under clear skies when the ground loses heat through radiation, leading to cooling of the air near the ground. High-inversion fog, on the other hand, typically forms in valleys when warm air traps cooler air below it, preventing it from mixing. Therefore, the specific mechanism of moist air being lifted over a mountain makes upslope fog the correct answer.
