🔍 Key Concepts

• Advection fog vs radiation fog – what is moving in each case? • Role of air temperature vs surface (water/land) temperature • How dew point and cooling of air to saturation create fog

💭 Think About

• Ask yourself: Does advection fog form because air is moving, or because the ground cools under still air at night? • Which option describes warm or cold air being transported (blown) over a surface with a different temperature, causing the air to cool to its dew point? • Which choices sound more like radiation fog or frontal (rain) fog instead of advection fog?

✅ Before You Answer

• Identify which answer choice clearly involves horizontal movement of air (advection) over a surface of different temperature. • Eliminate any options that describe mainly nighttime ground cooling with light winds (that’s a different type of fog). • Check which option would actually cool air down to the dew point, instead of warming it away from saturation.
