Which of the following climatic controls can be considered to be the most important?

a. longitude
b. elevation
c. latitude
d. storms

A. Longitude

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.
