Question 1233Navigation General

The correct answer is D) advection fog. Advection fog occurs when warm, moist air blows over a colder surface, causing the air to cool below its dew point. As the air cools, the water vapor in the air condenses, forming tiny water droplets suspended in the air, resulting in the formation of fog. This process is known as advection, where the movement of the air mass leads to the condensation of water vapor. The other options are incorrect because: A) Ice fog is caused by the condensation of water vapor in extremely cold air, not by warm moist air blowing over a colder surface. B) Radiation fog is formed when the ground cools due to radiative cooling, causing the air near the ground to cool below its dew point. C) Frost smoke, also known as sea smoke, is formed when cold air moves over much warmer water, not the other way around.
