Question

Quizplus · Accepted Answer

Radiation fog is formed when the clear sky allows for cooling of the ground, leading to a temperature inversion near the surface. Therefore, a clear sky is most conducive to the development of radiation fog. Option A is incorrect because warm air holds more water vapor, making it less likely for fog to form. Option B is incorrect because the presence of stratus clouds indicates more moisture in the air, which can hinder the development of radiation fog.
