Sokobanjska kotlina je mala oblast u centralnom delu istočne Srbije, jasno ograničena sa svih strana planinama, do 1600 metara nadmodske visine. Ona leži između planine Rtnja na severu, Ozrena, Leskovika i Device na jugu i izmedju moravske doline na zapadu i timočke na istoku. Ovako ograničena Sokobanjska kotlina zahvata površinu od 515,5 km2 i izdužena je u pravcu istok zapad. Sokobanjska kotlina predstavlja izolovanu geografsku celinu, ali ne sasvim, zbog nekih morfoloških elemenata. Preko bovanske na zapadu i skrobničke klisure na istoku, sokobanjska kotlina spaja moravski na jednoj (preko bovanske klisure) i timočki sliv (knjaževačkom klisurom) na drugoj strani. Pored ovog, sokobanjska kotlina je na severu, preko visokih presedlina Lukavice i Rasinackog sedla, vezana sa oblašću Crne reke, a na jugu preko Ozrena za golačka sela i moravsku dolinu. Ovo je stari put kojim su bili povezani Cma reka i Niš.
Europe is generally agreed to be the birthplace of western culture, including such legendary innovations as the democratic nation-state, football and tomato sauce.The word Europe comes from the Greek goddess Europa, who was kidnapped by Zeus and plunked down on the island of Crete. Europa gradually changed from referring to mainland Greece until it extended finally to include Norway and Russia.Don't be confused that Europe is called a continent without looking like an island, the way the other continents do. It's okay. The Ural mountains have steadily been there to divide Europe from Asia for the last 250 million years. Russia technically inhabits "Eurasia".Europe is presently uniting into one political and economic zone with a common currency called the Euro. The European Union originated in 1993 and is now composed of 27 member states. Its headquarters is in Brussels, Belgium.Do not confuse the EU with the Council of Europe, which has 47 member states and dates to 1949. These two bodies share the same flag, national anthem, and mission of integrating Europe. The headquarters of the Council are located in Strasbourg, France, and it is most famous for its European Court of Human Rights. In spite of these two bodies, there is still no single Constitution or set of laws applying to all the countries of Europe. Debate rages over the role of the EU in regards to national sovereignty. As of January 2009, the Lisbon Treaty is the closest thing to a European Constitution, yet it has not been approved by all the EU states. Text by Steve Smith.
