Question

Quizplus · Accepted Answer

Advection fog occurs when warm, moist air moves over a colder surface. As the air cools, the water vapor condenses into fog. Radiation fog occurs when the air near the ground cools overnight and water vapor condenses into fog. Steam fog occurs when cold air moves over warmer water and evaporated water rises to meet the cold air, causing condensation. Upslope fog occurs when air is forced up a mountain slope and cools, causing the water vapor to condense into fog.
