zone [Gr.,=girdle], in geography, area with a certain physical and/or cultural unity that distinguishes it from other areas. The division of the earth into five climatic zones probably originated (5th cent. B.C.) with Parmenides, who recognized a torrid zone (see tropics tropics, also called tropical zone or torrid zone, all the land and water of the earth situated between the Tropic of Cancer at lat. 23 1-2°N and the Tropic of Capricorn at lat. 23 1-2°S. .....

The zones are based on latitude: the torrid zone lies between 23 1-2°N and 23 1-2°S, the temperate zones between these parallels and the polar circles (66 1-2° N and S), and the frigid zones from the polar circles to the poles. Later geographers, recognizing that climate is affected by such conditions as altitude, distance from water, prevailing winds, and ocean currents, have used other bases for zoning. Most geographers today recognize five major climatic groups, based mainly on the work of the German meteorologist Wladimir Köppen. Two of these groups—the rainy tropics and the dry tropics, which encompass four different climates—together correspond roughly to the former torrid zone. Two humid climate groups of the Köppen system, encompassing six climates, together correspond roughly to the former temperate zones. Köppen's two polar climates correspond roughly to the two former frigid zones. In addition to the five groups encompassing twelve climates, geographers also recognize a series of highland zones where many of the other climates of the world are duplicated. Geographic zones in which people have similar patterns of life are called culture zones or areas (see culture culture, in anthropology, the integrated system of socially acquired values, beliefs, and rules of conduct which delimit the range of accepted behaviors in any given society. Cultural differences distinguish societies from one another. ..... Click the link for more information. ). An example would be the plains area of North America.

| Not to consider here anything except the Christian architecture of Europe, that younger sister of the great masonries of the Orient, it appears to the eyes as an immense formation divided into three well-defined zones, which are superposed, the one upon the other: the Romanesque zone*, the Gothic zone, the zone of the Renaissance, which we would gladly call the Greco-Roman zone. which, barred with various tints, seemed like the Andes' western slope, to show forth in one array, contrasting climates, zone by zone. In the spring, when the streams are swollen by rain and by the melting of the snows, the lake rises several feet above its ordinary level during the summer, it gradually subsides again, leaving a sparkling zone of the finest salt upon its shores. |
