Tuz Gölü
Anatolia's terrain is structurally complex. A central massif composed of uplifted blocks and downfolded troughs, covered by recent deposits and giving the appearance of a plateau with rough terrain, is wedged between two folded mountain ranges that converge in the east. True lowland is confined to a few narrow coastal strips along the Aegean, Mediterranean, and the Black Sea coasts. Flat or gently sloping land is rare and largely confined to the deltas of the Kızıl River, the coastal plains of Çukurova and the valley floors of the Gediz River and the Büyük Menderes River as well as some interior high plains in Anatolia, mainly around Lake Tuz (Salt Lake) and the Konya Basin ("Konya Ovasi").
