WebAug 2, 2024 · Fog forms in the same way as cloud, except the process takes place at the surface rather than higher in the atmosphere. For both fog and clouds to form, the air temperature needs to cool to the dew-point temperature —the temperature at which condensation occurs.

Explain that fog is formed when the difference between the air temperature and the dew point is less than 2.5 °C (4.5 °F). When water vapor condenses into small liquid water droplets suspended in the air, fog begins to form.
WebJan 4, 2016 · Dew, fog and clouds result even when the temperature is higher than the freezing point. Forms of condensation may also be classified on the basis of their location, i.e. at or near the earth’s surface and in free air. Dew, white frost, fog and mist come in the first category, whereas clouds are in the second category. Dew
