Task: Instance Description Understanding (ontology: Earth_Environment/SWEET)

Which of the following definitions best describes the instance 'adiabatic'?

A. the instance climate classification, also known as the arid climate classification, is characterized by having precipitation amounts less than 1/2 potential evapotranspiration (POTET).
B. A process in which a system does not interact with its surroundings by virtue of a temperature difference between them.
C. the instance climate classification is characterized by winter drought and warmest month temperatures above 22 degree C.
D. A moist-adiabatic process in which the liquid water that condenses is assumed to be removed as soon as it is formed, by idealized instantaneous precipitation.

Answer: A process in which a system does not interact with its surroundings by virtue of a temperature difference between them.
