The wind blows from the city to the suburbs.
Work Step by Step
Using the result of the previous question, soil warms up and cools off faster than concrete.
There is less concrete in the suburbs than in the city, so during the day,
the suburbs will warm up faster than the city.
Warm air rises and is replaced by colder air, coming from the city.
Moving air = wind.
The wind blows from the city to the suburbs.
