Answer: A. Longitude
Step-by-step explanation:
A lot of factors contribute to the climate of a region. These include:
Elevation: this affects temperature, pressure and in turn condensation. Pressure decreases the higher you go, as does temperature.
Latitude: this has an inverse relationship with temperature. The lower the latitude of a region, the higher the temperature.
Storms: Winds are in control of air masses and affect condensation as well as temperature changes.
However, Longitude is not one of these factors.
