11. At a specific location, the temperature at the surface is 13 degrees Celsius. Under thermal inversion conditions, the temperature at 4 km might be (a) 13 degrees Celsius (c) 20 degrees Celsius (b) -13 degrees Celsius (d) -20 degrees Celsius

(b) -13 degrees Celsius

Explanation:

Temperature inversion is simply the change in temperature with height or altitude.

It is a common phenomenon in the troposphere as we know that the higher one ascends, the cooler/colder it becomes.

Typically, there is a 6°C drop in temperature per km;

                          6°C drop in 1km

        for 4km, there would be a temperature drop of about 24°C;

The temperature at 4km will be 13-24  = -11°C

The closest value to this from the given options is -13°C

A. through the character's thoughts
