Question 1 of 27070

Advection fog, a common occurrence on the Great Lakes, forms when __________.

🔍 Key Concepts

• Advection fog vs. radiation fog – what’s the difference in how they form? • Role of horizontal movement of air (wind) over a surface of different temperature • How water temperature vs. air temperature affects saturation and condensation over large lakes or oceans

💭 Think About

• Is advection fog primarily about the land cooling at night, or about air moving over a surface with a different temperature? • On the Great Lakes, when you hear “advection fog,” should you picture warm air moving over colder water, or cold air moving over warmer water? • Which choice best matches the idea of air being cooled from below until it reaches its dew point over a broad water surface?

✅ Before You Answer

• Identify which option clearly involves air moving (advecting) horizontally over a surface. • Check which scenario would cause air to be cooled from below until it becomes saturated (reaches its dew point). • Eliminate any option that mainly describes nighttime land cooling or local river effects rather than broad-lake or ocean-scale processes.
