Question

1. what types of fog depend upon wind in order to exist?

○a. radiation fog and ice fog.
○b. steam fog and ground fog.
○c. advection fog and upslope fog.

Explanation:

Advection fog forms when warm, moist air moves (advects) over a cooler surface. The wind is crucial for the advection process. Upslope fog occurs when moist air is forced up a slope (like a mountain slope). Wind is needed to push the air up the slope. Radiation fog forms on clear, calm nights (so no wind dependence for its existence in the sense of the question). Ice fog, steam fog, and ground fog also do not have the same wind - dependence as advection and upslope fog for their basic formation mechanisms related to the presence requirement.

Answer:

C. Advection fog and upslope fog.
