Answer 1

We begin by defining what an isotherm is :

Isotherm — line on a map joining places of the same temperature at a given time or at a given period.

Isotherm 0 degrees centigrade represents the freezing level.

It represents the altitude at which the temperature is 0 in the atmosphere.

Above the freezing altitude the temperature is below freezing.
