Question 1 of 27070

Steam fog is most likely to occur on the Mississippi and Ohio Rivers in __________.

🔍 Key Concepts

• Steam fog (arctic/evaporation fog) forms when very cold air moves over relatively warm water • Seasonal water temperature patterns on inland rivers like the Mississippi and Ohio • Typical time of day when air is coldest vs when water retains heat

💭 Think About

• Think about which season on these rivers has water that is still relatively warm while the air above it can turn much colder. • At what time of day is the air temperature usually at its lowest compared to the water temperature? Early morning, midday, or evening? • Which combination of season and time of day would give you the largest temperature difference between the cold air and warmer river water?

✅ Before You Answer

• Be sure you understand that steam fog needs cold air over warmer water, not warm air over cold water. • Consider that river water temperature changes more slowly than air temperature with the seasons. • Check which answer best matches a time when the air is coolest but the water can still be relatively warm on these rivers.
