The change in air temperature caused by changes in air pressure is referred to as which of the following? a. Katabatic process. b. Adiabatic process. c. Abiotic process. d. Humidity process.

Option b.

Explanation:

The change in air temperature caused by changes in air pressure is referred to an adiabatic process, in wich the energy is transferred to the surroundings as work.  

In an adiabatic process, an increase of the pressure of a gas (e.g., air) will cause an increase in the temperature, because of the compression of the gas by the work done on it by its surroundings, and on the contrary, a decrease of the pressure of a gas will produce an expansion of the gas that will cause it to do work on its surroundings and hence the temperature will decrease.  

In the other processes mentioned, that is to say, katabatic process, abiotic process, and humidity process, a change in air pressure doesn't produce a change in the temperature.

Hence, the correct option is b, adiabatic process.
