Given below are two statements, one labelled as Assertion (A) and the other as Reason (R): Assertion (A): Poleward margins of hot desert regions experience dry and stable conditions due to descending air associated with the subtropical high pressure belt. Reason (R): Descending air in subtropical highs undergoes adiabatic cooling which increases relative humidity and promotes dry conditions.
