Advection fog, a common occurrence on the Great Lakes, forms when _______________.

AI Explanation
The correct answer is D) relatively warm air flows over cooler water. Advection fog forms when relatively warm, moist air flows over a cooler surface, such as a body of water. On the Great Lakes, this commonly occurs when warm air from the south moves northward and encounters the cooler lake waters, causing the air to cool and become saturated, resulting in the formation of advection fog. The other options are incorrect because they do not accurately describe the specific conditions that lead to the formation of advection fog, which is the type of fog commonly experienced on the Great Lakes.
