Advection fog holds longest over which portions of the lakes?

AI Explanation
The correct answer is C) Northwest. Advection fog is caused by the movement of warm, moist air over a cooler surface, such as a lake or ocean. The northwest portions of lakes tend to experience the longest duration of advection fog because the prevailing winds in many regions blow from the west or southwest, carrying the warm, moist air over the cooler lake surface in the northwest direction. The other options are incorrect because the southeast, northeast, and southwest portions of lakes are less likely to experience the prolonged presence of advection fog due to the direction of the prevailing winds.
