Answer:
D. its base at or near the ground
Explanation:
Technically fog is humidity that condenses near the ground. They are extremely small water droplets that are suspended near the surface. The relative humidity must be above 90% for fog to occur. Light wind or calm (lack of wind) is another important condition for the formation of the phenomenon.
The fog is a cloud, but with the base near the ground. It is a phenomenon that requires high humidity in the air always above 90% and reduces the horizontal visibility to less than 1,000 meters. Sometimes the fog gets so thick it can drizzle. The influence of high atmospheric pressure systems that cause thermal inversion facilitates the occurrence of fog.
