Question 1344Navigation General70% to pass
On the Mississippi and Ohio Rivers, there is a special type of fog known as steam fog. It is caused by _______________.
AI Explanation
The correct answer is C) cold air passing over much warmer water.
Steam fog, also known as advection fog, is caused by the rapid cooling of the air as it passes over much warmer water. The temperature difference between the cold air and the warmer water causes the water vapor in the air to condense, forming a thick, low-lying fog. This type of fog is commonly observed on the Mississippi and Ohio Rivers, where the water temperatures can be significantly warmer than the surrounding air.
The other options are incorrect because they do not accurately describe the formation of steam fog. Option A is incorrect as steam fog is not caused by rapid cooling of the ground at night. Option B is incorrect as steam fog is not formed by rain coming out of a warm air mass aloft. Option D is incorrect as the temperature difference must be between the cold air and the warmer water, not the other way around.
