Anatolia is a large, roughly rectangular peninsula situated bridge like between Europe and Asia. The Anatolian part of Turkey accounts for 97% of the country's area. It is also known as Asia Minor, Asiatic Turkey or the Anatolian Plateau. The term Anatolia is most frequently used in specific reference to the large, semiarid central plateau, which is rimmed by hills and mountains that in many places limit access to the fertile, densely settled coastal regions.

Geology

Turkey's varied landscapes are the product of a wide variety of tectonic processes that have shaped Anatolia over millions of years and continue today as evidenced by frequent earthquakes and occasional volcanic eruptions.

However, many of the rocks exposed in Turkey were formed long before this process began. Turkey contains outcrops of Precambrian rocks, (more than 540 million years old; Bozkurt et al., 2000).

Regions

According to worldofturkey.com

The 1st Geography Congress, held in Ankara between 6–21 June 1941, divided Turkey into seven regions after long discussions and work. These geographical regions were separated according to their climate, location, flora and fauna, human habitat, agricultural diversities, transportation, topography and so on. At the end, 4 side regions and 3 inner regions were named according to their neighborhood to the four seas surrounding Turkey and positions in Anatolia.


Distinct contrasts between the interior and periphery of Turkey are manifested in its landform regions, climate, soils, and vegetation. The periphery is divided into the Black Sea region, the Marmara region, the Aegean region, and the Mediterranean region. The interior is divided into three regions: Central Anatolia, Eastern Anatolia and Southeastern Anatolia.

Black Sea Region

The Black Sea region has a steep, rocky coast with rivers that cascade through the gorges of the coastal ranges. A few larger rivers, those cutting back through the Pontic Mountains
Pontic Mountains

, form an almost unbroken wall separating the coast from the interior. The higher slopes facing northwest tend to be densely forested. Because of these natural conditions, the Black Sea coast historically has been isolated from Anatolia.

 is world-renowned for the production of hazelnuts, and farther east the Rize region has numerous tea plantations. All cultivable areas, including mountain slopes wherever they are not too steep, are sown or used as pasture. The mild, damp climate of the Black Sea coast makes commercial farming profitable. The western part of the Black Sea region, especially the Zonguldak area, is a center of coal mining and heavy industry.

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.

Marmara Region

Densely populated, this area includes the cities of Istanbul

. 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.

Central Anatolia 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.

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.

Eastern and Southeastern Anatolia Regions

Eastern Anatolia, where the Pontus and Taurus mountain ranges converge, is rugged country with higher elevations, a more severe climate, and greater precipitation than are found on the Anatolian Plateau. The region is known as the Anti-Taurus, and the average elevation of its peaks exceeds 3,000 meters. Mount Ararat

. Several small streams that empty into the Black Sea or landlocked Lake Van also originate in these mountains.

In addition to its rugged mountains, the area is known for severe winters with heavy snowfalls. The few valleys and plains in these mountains tend to be fertile and to support diverse agriculture. The main basin is the Mus Valley, west of Lake Van. Narrow valleys also lie at the foot of the lofty peaks along river corridors.

Southeast Anatolia is south of the Anti-Taurus Mountains. It is a region of rolling hills and a broad plateau surface that extends into Syria. Elevations decrease gradually, from about 800 meters in the north to about 500 meters in the south. Traditionally, wheat and barley

Climate

Turkey's diverse regions have different climates, with the weather system on the coasts contrasting with that prevailing in the interior. The Aegean and Mediterranean coasts have cool, rainy winters and hot, moderately dry summers. Annual precipitation in those areas varies from 580 to 1300 mm (22.8 to 51.2 in), depending on location. Generally, rainfall is less to the east. The 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 2500 millimetres (98.4 in) annually which is the highest precipitation in the country.
Mountains close to the coast prevent Mediterranean influences from extending inland, giving the interior of Turkey a continental climate with distinct seasons. The Anatolian Plateau is much more subject to extremes than are the coastal areas. Winters on the plateau are especially severe. Temperatures of -30 C can occur in the mountainous areas in the east, and snow may lie on the ground 120 days of the year. In the west, winter temperatures average below 1 °C (33.8 °F). Summers are hot and dry, with temperatures above 30 °C (86 °F). Annual precipitation averages about 400 millimetres (15.7 in) , with actual amounts determined by elevation. The driest regions are the Konya Ovasi and the Malatya Ovasi, where annual rainfall frequently is less than 300 millimetres (11.8 in). May is generally the wettest month and July and August the driest.

The climate of the Anti-Taurus Mountain region of eastern Turkey can be inhospitable. Summers tend to be hot and extremely dry. Winters are bitterly cold with frequent, heavy snowfall. Villages can be isolated for several days during winter storms. Spring and autumn are generally mild, but during both seasons sudden hot and cold spells frequently occur.
