Question

With respect to advection fog, which statement is true?

1) Advection fog is formed when warm air moves over a cold surface.
2) Advection fog is formed when cold air moves over a warm surface.
3) Advection fog is formed due to the cooling of air near the ground.
4) Advection fog is formed due to the condensation of water vapor in the air.

Answer 1

Advection fog is formed when warm air moves over a cold surface.

Step-by-step explanation:

Advection fog is formed when warm air moves over a cold surface. This is true because the warm air cools down when it comes in contact with the cold surface, causing the water vapor in the air to condense and form fog.
