The European portion of the Aegean region consists mainly of rolling plateau country well suited to agriculture. It receives about 520 millimeters of rainfall annually. Densely populated, this area includes the cities of Istanbul and Edirne. The Bosporus, which links the Sea of Marmara and the Black Sea, is about twenty-five kilometers long and averages 1.5 kilometers in width but narrows in places to less than 500 meters. Both its Asian and European banks rise steeply from the water and form a succession of cliffs, coves, and nearly landlocked bays. Most of the shores are densely wooded and are marked by numerous small towns and villages. The Dardanelles Strait, which links the Sea of Marmara and the Aegean Sea, is approximately forty kilometers long and increases in width toward the south. Unlike the Bosporus, the Dardanelles has few settlements along its shores.

On its Asian side, the Aegean region has fertile soils and a typically Mediterranean climate with mild, wet winters and hot, dry summers. The broad, cultivated valley lowlands contain about half of the country's richest farmland. Major crops are olives, citrus, nuts (especially almonds), and tobacco. The most important valleys are the Kocaeli Valley, the Bursa Ovasi (Bursa Basin), and the Plains of Troy. The valley lowlands are densely populated, particularly around Bursa and Izmir, the country's third largest city and a major manufacturing center.

Mediterranean Region

The narrow coastal plains of the Mediterranean region, separated from Anatolia by the Taurus Mountains, which reach elevations of 2,000 to 2,750 meters, are cultivated intensively. Fertile soils and a warm climate make the Mediterranean coast ideal for growing citrus fruits, grapes, figs, bananas, various vegetables, barley, wheat, and, in irrigated areas, rice and cotton. The Cukur Ova in the east is a plain that is the most developed agricultural area of the Mediterranean region. It is a significant cotton-growing center and also supports a major cotton-based textile industry. In general, summers are hot and dry in the Mediterranean region. The weather in combination with the region's numerous sandy beaches has encouraged the development of a tourist industry.

Toward the east, the extensive plains around Adana, Turkey's fourth largest city, consist largely of reclaimed flood lands. In general, rivers have not cut valleys to the sea in the western part of the region. Historically, movement inland from the western Mediterranean coast was difficult. East of Adana, much of the coastal plain has limestone features such as collapsed caverns and sinkholes. Between Adana and Antalya, the Taurus Mountains rise sharply from the coast to high elevations. Other than Adana, Antalya, and Mersin, the Mediterranean coast has few major cities, although it has numerous farming villages.
