Kazakhstan is the world's largest landlocked country, and the ninth largest in the world, with an area of . Kazakhstan is the dominant nation of Central Asia economically, generating 60% of the region's GDP, primarily through its oil/gas industry. It also has vast mineral resources. The Caspian Sea is the largest enclosed inland body of water on Earth by area, variously classed as the world's largest lake or a full-fledged sea. It is in an endorheic basin (it has no outflows) located between Europe and Asia. It is bound by Kazakhstan to the northeast, Russia to the northwest, Azerbaijan to the west, Iran to the south, and Turkmenistan to the southeast. The Danube (, known by various names in other languages) is Europe's second-longest river, after the Volga River, and also the longest river in the European Union region. It is located in Central and Eastern Europe. Russia (from the  Rus'), also officially known as the Russian Federation, is a country in Eurasia. At , Russia is the largest country in the world by surface area, covering more than one-eighth of the Earth's inhabited land area, and the ninth most populous, with over 140 million people at the end of March 2016. The European western part of the country is much more populated and urbanised than the eastern, about 77% of the population live in European Russia. Russia's capital Moscow is one of the largest cities in the world, other major urban centers include Saint Petersburg, Novosibirsk, Yekaterinburg, Nizhny Novgorod and Samara. Orenburg is the administrative center of Orenburg Oblast (region), Russia, lies on the River Ural, southeast of Moscow. Its geographical location is in the boundary of Europe and Asia. Orenburg is also very close to the border with Kazakhstan. Population: 548,331 (2010 Census); 549,361 (2002 Census);  Russia is not proportionately populated between the smaller western portion (almost 25%) of the country that is considered part of Europe, and the larger eastern portion (more than 75%) that is part of Asia. European Russia contains about 77% of the country's population (110,000,000 people out of about 144,000,000) in an area comprising almost 4 million km (1.54 million mi); an average of 27.5 persons per km (70 per mi). This territory makes up 38% of Europe. Its eastern border is defined by the Ural Mountains and in the south, it is defined by the border with Kazakhstan. This area includes Moscow and Saint Petersburg, the two largest cities in Russia. The Ural Mountains, or simply the Urals, are a mountain range that runs approximately from north to south through western Russia, from the coast of the Arctic Ocean to the Ural River and northwestern Kazakhstan.
  The mountain range forms part of the conventional boundary between the continents of Europe and Asia. Vaygach Island and the islands of Novaya Zemlya form a further continuation of the chain to the north into the Arctic Ocean. Asia is Earth's largest and most populous continent, located primarily in the eastern and northern hemispheres and sharing the continental landmass of Eurasia with the continent of Europe. Asia covers an area of , about 30% of Earth's total land area and 8.7% of the Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Asia is notable for not only its overall large size and population, but also dense and large settlements as well as vast barely populated regions within the continent of 4.4 billion people. Yekaterinburg, alternatively romanised as "Ekaterinburg", is the fourth-largest city in Russia and the administrative centre of Sverdlovsk Oblast, located in the middle of the Eurasian continent, on the border of Europe and Asia. At the 2010 Census, it had a population of 1,349,772. Sakmara River ( Russian :  ; Bashkir :  , Haqmar ) is a river in Russia that drains the southern tip of the Ural Mountains south into the Ural River . It is 760 kilometres ( 470 mi ) long . It is a tributary of the Ural River , which it meets in Orenburg . The source of the Sakmara River is in the Republic of Bashkortostan . Other towns along the Sakmara are Yuldybayevo ( Bashkortostan ) , Kuvandyk , and railway station Saraktash clouse to the Wozdwizhenskaya Fortress ( Orenburg Oblast ) . It rises in the southern Ural Mountains about 60 kilometres ( 37 mi ) west - southwest of Magnitogorsk and flows south through a valley with some canyon development . At Kuvandyk it swings west , leaves the mountains and flows west parallel to the Ural River with many meanders for about 150 kilometres ( 93 mi ) ( straight - line distance ) before turning south to meet the Ural . Major tributaries are the Salymysh River and the Bolshoy Ik River , both from the north . Eurasia is the combined continental landmass of Europe and Asia. The term is a portmanteau of its constituent continents. Located primarily in the Northern and Eastern Hemispheres, it is bordered by the Atlantic Ocean to the west, the Pacific Ocean to the east, the Arctic Ocean to the north, and by Africa, the Mediterranean Sea, and the Indian Ocean to the south. The division between Europe and Asia as two different continents is a historical and cultural construct, with no clear physical separation between them; thus, in some parts of the world, Eurasia is recognized as the largest of five or six continents. In geology, Eurasia is often considered as a single rigid megablock. However, the rigidity of Eurasia is debated based on the paleomagnet data. The Ural or Jayq/Zhayyq (, ), known as Yaik before 1775, is a river flowing through Russia and Kazakhstan in Eurasia. It originates in the southern Ural Mountains and ends at the Caspian Sea. At , it is the third-longest river in Europe after the Volga and the Danube, and the 18th-longest river in Asia. The Ural River is conventionally considered part of the boundary between the continents of Europe and Asia. Novaya Zemlya (lit. "new land"), also known, especially in Dutch, as Nova Zembla, is an archipelago in the Arctic Ocean in northern Russia and the extreme northeast of Europe, the easternmost point of Europe lying at Cape Flissingsky on the Northern island. Administratively, it is incorporated as Novaya Zemlya District, one of the twenty-one in Arkhangelsk Oblast, Russia. Municipally, it is incorporated as Novaya Zemlya Urban Okrug.  Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, and the Mediterranean Sea to the south. To the east and southeast, Europe is generally considered as separated from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways of the Turkish Straits. Yet the non-oceanic borders of Europea concept dating back to classical antiquityare arbitrary. The primarily physiographic term "continent" as applied to Europe also incorporates cultural and political elements whose discontinuities are not always reflected by the continent's current overland boundaries. The Kazakhs (also spelled Kazaks, Qazaqs , , ; the English name is transliterated from Russian) are a Turkic people who mainly inhabit the southern part of Eastern Europe Ural mountains and northern parts of Central Asia (largely Kazakhstan, but also found in parts of Uzbekistan, China, Russia and Mongolia), the region also known as Eurasian sub-continent. Kazakh identity is of medieval origin and was strongly shaped by the foundation of the Kazakh Khanate between 1456 and 1465, when several tribes under the rule of the sultans Zhanibek and Kerey departed from the Khanate of Abu'l-Khayr Khan.
