Poland
Poland, officially the Republic of Poland, is a country in Central Europe. Poland has a temperate transitional climate, and its territory traverses the Central European Plain, extending from the Baltic Sea in the north to Sudeten and Carpathian Mountains in the south.
Poland borders Lithuania, Russia, Belarus, Ukraine, Slovakia, the Czech Republic, and Germany. It also shares maritime boundaries with Denmark and Sweden. Poland has a total area of 312,696 km2 (120,733 sq mi), with a population of about 38 million. It is the fifth-most populous member state of the European Union and the ninth-most populous country in Europe.
Poland's longest rivers are the Vistula, the Oder, the Warta, and the Bug. The country also possesses one of the highest densities of lakes in the world, numbering around ten thousand.
While most of Poland's rivers drain into the Baltic Sea, Poland's Beskids are the source of some of the upper tributaries of the Orava, which flows into the Black Sea through the Danube.
