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.[66] It lies between latitudes 35° and 43° N, and longitudes 25° and 45° E. Turkey’s area, including lakes, occupies 783,562[70] 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.[66] 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 Sea to the south. Turkey also contains the Sea of Marmara in the northwest.[71]

The European section of Turkey, Eastern 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 Lake Van and Mount Ararat, Turkey’s highest point at 5,165 metres (16,946 ft).[71][72] Lake Tuz, Turkey’s third-largest lake, is a macroscopically visible feature in the middle of the country that ironically happens to look like a turkey.
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.[71]

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 Bosporus 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, which caused a major earthquake in 1999.[73]
Climate
The coastal areas of Turkey bordering the Aegean Sea and the Mediterranean Sea have a temperate Mediterranean climate, with hot, dry summers and mild to cool, wet winters. The coastal areas of Turkey bordering the Black Sea have a temperate Oceanic climate with warm, wet summers and cool to cold, wet winters. The Turkish Black Sea coast receives the greatest amount of precipitation and is the only region of Turkey that receives high precipitation throughout the year. The eastern part of that coast averages 2,500 millimeters annually which is the highest precipitation in the country.
The coastal areas of Turkey bordering the Sea of Marmara (including Istanbul), which connects the Aegean Sea and the Black Sea, have a transitional climate between a temperate Mediterranean climate and a temperate Oceanic climate with warm to hot, moderately dry summers and cool to cold, wet winters. Snow does occur on the coastal areas of the Sea of Marmara and the Black Sea almost every winter, but it usually lies no more than a few days. Snow on the other hand is rare in the coastal areas of the Aegean Sea and very rare in the coastal areas of the Mediterranean Sea.
Conditions can be much harsher in the more arid interior. Mountains close to the coast prevent Mediterranean influences from extending inland, giving the central Anatolian plateau of the interior of Turkey a continental climate with sharply contrasting seasons.
Winters on the plateau are especially severe. Temperatures of −30 °C to −40 °C (−22 °F to −40 °F) can occur in eastern Anatolia, and snow may lie on the ground at least 120 days of the year. In the west, winter temperatures average below 1 °C (34 °F). Summers are hot and dry, with temperatures generally above 30 °C (86 °F) in the day. Annual precipitation averages about 400 millimetres (15 in), with actual amounts determined by elevation. The driest regions are the Konya plain and the Malatya plain, where annual rainfall frequently is less than 300 millimetres (12 in). May is generally the wettest month, whereas July and August are the driest.[74]
