Turkey is a transcontinental Eurasian country.
Asian Turkey (made up largely of Anatolia), which includes 97% of the country, is separated from European Turkey by the Bosphorus, the Sea of Marmara, and the Dardanelles.
European Turkey comprises 3% of the country.
The territory of Turkey is more than 1,600 kilometres (1,000 mi) long and 800 km (500 mi) wide, with a roughly rectangular shape.
It lies between latitudes 35° and 43° N, and longitudes 25° and 45° E. Turkey's area, including lakes, occupies 783,562 square kilometres (300,948 sq mi), of which 755,688 square kilometres (291,773 sq mi) are in Southwest Asia and 23,764 square kilometres (9,174 sq mi) in Europe.
Turkey is the world's 37th-largest country in terms of area.
The country is encircled by seas on three sides: the Aegean Sea to the west, the Black Sea to the north and the Mediterranean to the south.
Turkey also contains the Sea of Marmara in the northwest.
The European section of Turkey, East Thrace, forms the borders of Turkey with Greece and Bulgaria.
The Asian part of the country, Anatolia, consists of a high central plateau with narrow coastal plains, between the Köroğlu and Pontic mountain ranges to the north and the Taurus Mountains to the south.
Eastern Turkey has a more mountainous landscape and is home to the sources of rivers such as the Euphrates, Tigris and Aras, and contains Mount Ararat, Turkey's highest point at 5,137 metres (16,854 ft), and Lake Van, the largest lake in the country.
Turkey is divided into seven census regions: Marmara, Aegean, Black Sea, Central Anatolia, Eastern Anatolia, Southeastern Anatolia and the Mediterranean.
The uneven north Anatolian terrain running along the Black Sea resembles a long, narrow belt.
This region comprises approximately one-sixth of Turkey's total land area.
As a general trend, the inland Anatolian plateau becomes increasingly rugged as it progresses eastward.
Turkey's varied landscapes are the product of complex earth movements that have shaped the region over thousands of years and still manifest themselves in fairly frequent earthquakes and occasional volcanic eruptions.
The Bosphorus and the Dardanelles owe their existence to the fault lines running through Turkey that led to the creation of the Black Sea.
There is an earthquake fault line across the north of the country from west to east, along which a major earthquake occurred in 1999.
The Dead Sea Transform (DST) fault system, also sometimes referred to as the Dead Sea Rift, is a series of faults that run from the Maras Triple Junction (a junction with the East Anatolian Fault in southeastern Turkey) to the northern end of the Red Sea Rift (just offshore of the southern tip of the Sinai Peninsula).
The fault system forms the transform boundary between the African Plate to the west and the Arabian Plate to the east.
It is a zone of left lateral displacement, signifying the relative motions of the two plates.
Both plates are moving in a general north-northeast direction, but the Arabian Plate is moving faster, resulting in the observed left lateral motions along the fault of approximately 107 km.
A component of extension is also present in the southern part of the transform, which has contributed to a series of depressions, or pull apart basins, forming the Gulf of Aqaba, Dead Sea, Sea of Galilee and Hula basins. 
The North Anatolian Fault (NAF) () is an active right-lateral strike-slip fault in northern Anatolia which runs along the transform boundary between the Eurasian Plate and the Anatolian Plate.
The fault extends westward from a junction with the East Anatolian Fault at the Karliova Triple Junction in eastern Turkey, across northern Turkey and into the Aegean Sea.
It runs about 20 km south of Istanbul.
The North Anatolian Fault is similar in many ways to the San Andreas Fault in California.
Both are continental transforms with similar lengths and slip rates.
The Sea of Marmara near Istanbul is an extensional basin similar to the Salton Trough in California, where a releasing bend in the strike-slip system creates a pull apart basin. 
The Dead Sea Transform is a transform fault that spans from the Red Sea in the south to the East Anatolian Fault to the north in Turkey.
The southern extent of the DST is known as the Wadi Araba fault (after the Arabah valley).
This portion of the DST runs from north of Aqaba to south of the Dead Sea and has a slip rate of 4 ±2 mm per year. 
Very severe earthquakes, especially on the North Anatolian Fault and East Anatolian Fault, occur along an arc extending from the Sea of Marmara in the west to Lake Van in the east.
On August 17, 1999, a 7.4-magnitude earthquake struck northwestern Turkey, killing more than 17,000 and injuring 44,000.
