Regiones

Adam of Bremen himself compared the sea with a belt, stating that it is so named because it stretches through the land as a belt (Balticus, eo quod in modum baltei longo tractu per Scithicas regiones tendatur usque in Greciam).

Administrative divisions Peru's territory, according to the Regionalization Law which was passed on 18 November 2002, is divided into 25 regions (regiones).

Physical characteristics Composition Depiction of Ganymede centered over 45° W. longitude; dark areas are Perrine (upper) and Nicholson (lower) regiones; prominent craters are Tros (upper right) and Cisti (lower left).
