Question 1231Navigation General

The correct answer is C) extremely cold air from shore passes over warmer water. The formation of steam smoke, also known as sea smoke, occurs when extremely cold air from the shore passes over warmer water. The temperature difference between the cold air and the warmer water causes the water to rapidly evaporate, creating a visible cloud of water vapor or steam over the water's surface. The other options are incorrect because they do not accurately describe the specific conditions that lead to the formation of steam smoke. Options A and B involve the interaction of warm and cold air masses, but do not specifically mention the key factor of extremely cold air passing over warmer water. Option D describes the opposite scenario, where warm dry air passes over cooler water, which would not result in the formation of steam smoke.
