Question

T or F

Answer 1

That statement is true. The cold surface will cool the warm, moist air to the dew point, and condensation will occur.

True.

Advection fog occurs when moist air passes over a cool surface by advection (wind) and is cooled. It is common as a warm front passes over an area with significant snowpack.
