Geography of Poland
Poland is a country in East-Central Europe with an area of 312,679 square kilometres (120,726 sq. mi.), and mostly temperate climate. Generally speaking, Poland is an almost unbroken plain reaching from the Baltic Sea in the north, to the Carpathian Mountains in the south. Within that plain, terrain variations run in bands east to west. 
The Baltic coast has two natural harbors, the larger one in the Gdańsk-Gdynia region, and a smaller one near Szczecin in the far northwest. The northeastern region, also known as the Masurian Lake District with more than 2,000 lakes, is densely wooded and sparsely populated. To the south of the lake district, and across central Poland a vast region of plains extends all the way to the Sudetes on the Czech and Slovak borders southwest, and to the Carpathians on the Czech, Slovak and Ukrainian borders southeast. The central lowlands had been formed by glacial erosion in the Pleistocene ice age. The neighboring countries are Germany to the west, the Czech Republic and Slovakia to the south, Ukraine and Belarus to the east, and Lithuania and the Russian exclave of Kaliningrad to the northeast.
