The physical process is the same as cloud formation, but the location is different. Statement 2 is correct: Radiation fog forms under clear skies, when the ground loses heat rapidly through radiation, cooling the layer of air immediately above it below its dew point. This cooling leads to condensation and fog formation. Statement 3 is correct: Advection fog forms when warm, moist air moves horizontally over a cooler surface (land or water). As the warm air passes over the cold surface, it is cooled from below, causing the water vapor to condense and form fog.<br \/>\n<\/section>\n","protected":false},"excerpt":{"rendered":"<p>Consider the following statements on \u2018Fog\u2019: 1.
