Final answer:
Fog is the type of cloud that forms close to the ground when the temperature is just above the dew point.
Step-by-step explanation:
The type of cloud that forms close to the ground when the temperature is just above the dew point is fog. Fog is a low-lying cloud that forms when warm, moist air comes into contact with a cooler surface and cools to its dew point, causing water vapor to condense into tiny water droplets.
