Turkey Pontus and Taurus Mountains
Sources: The Library of Congress Country Studies; CIA World Factbook
The Pontus Mountains (also called the North Anatolian Mountains) in the north are an interrupted chain of folded highlands that generally parallel the Black Sea coast. In the west, the mountains tend to be low, with elevations rarely exceeding 1,500 meters, but they rise in an easterly direction to heights greater than 3,000 meters south of Rize. Lengthy, troughlike valleys and basins characterize the mountains. Rivers flow from the mountains toward the Black Sea. The southern slopes--facing the Anatolian Plateau--are mostly unwooded, but the northern slopes contain dense growths of both deciduous and evergreen trees.
Paralleling the Mediterranean coast, the Taurus (Toros Daglari) is Turkey's second chain of folded mountains. The range rises just inland from the coast and trends generally in an easterly direction until it reaches the Arabian Platform, where it arcs around the northern side of the platform. The Taurus Mountains are more rugged and less dissected by rivers than the Pontus Mountains and historically have served as a barrier to human movement inland from the Mediterranean coast except where there are mountain passes such as the Cilician Gates (Gülek Bogazi), northwest of Adana.
Frequently interspersed throughout the folded mountains, and also situated on the Anatolian Plateau, are well-defined basins, which the Turks call ova . Some are no more than a widening of a stream valley; others, such as the Konya Ovasi, are large basins of inland drainage or are the result of limestone erosion. Most of the basins take their names from cities or towns located at their rims. Where a lake has formed within the basin, the water body is usually saline as a result of the internal drainage--the water has no outlet to the sea.
Stretching inland from the Aegean coastal plain, the Anatolian Plateau occupies the area between the two zones of the folded mountains, extending east to the point where the two ranges converge. The plateau-like, semiarid highlands of Anatolia are considered the heartland of the country. The region varies in elevation from 600 to 1,200 meters from west to east. The two largest basins on the plateau are the Konya Ovasi and the basin occupied by the large salt lake, Tuz Gölü. Both basins are characterized by inland drainage. Wooded areas are confined to the northwest and northeast of the plateau. Rain-fed cultivation is widespread, with wheat being the principal crop. Irrigated agriculture is restricted to the areas surrounding rivers and wherever sufficient underground water is available. Important irrigated crops include barley, corn, cotton, various fruits, grapes, opium poppies, sugar beets, roses, and tobacco. There also is extensive grazing throughout the plateau.
The Anatolian Plateau receives little annual rainfall. For instance, the semiarid center of the plateau receives an average yearly precipitation of only 300 millimeters. However, actual rainfall from year to year is irregular and occasionally may be less than 200 millimeters, leading to severe reductions in crop yields for both rain-fed and irrigated agriculture. In years of low rainfall, stock losses also can be high. Overgrazing has contributed to soil erosion on the plateau. During the summers, frequent dust storms blow a fine yellow powder across the plateau. Locusts occasionally ravage the eastern area in April and May. In general, the plateau experiences extreme heat, with almost no rainfall in summer and cold weather with heavy snow in winter.
