Zone
ZONE (Gr. &vri, a girdle, from favvvvai, to gird), a term for a belt or girdle, now used chiefly in the transferred sense of a demarcated area. Thus the earth's surface is divided, for classification of climates, into five climatic zones: the two temperate and the two frigid zones and the tropical or torrid zone. (See CLIMATE AND CLIMATOLOGY.)
