What is the geographical environment of Poland?
Poland has a flat terrain, and most of its territory lies in the low Bode Plain, with slight fluctuation, with an average elevation of173m. The plains below 200 meters above sea level account for about 72% of the country's area. The terrain is high in the south and low in the north, and the middle part is concave. There are many moraine lakes in the north, low hills in the south, Sutede Mountain and beskid mountains near the Czech border. The northeast lake area is densely forested and sparsely populated.
The main mountain ranges in Poland are Carpathian and Sudetenland. Among them, the Carpathian Mountains form Poland's borders with the Czech Republic, Slovakia and Ukraine.
Apart from Gdansk, Poland lacks natural ports along the Baltic Sea. Located in the northwest, Szczecin is an important port in Poland.
The larger rivers are the Vistula River (length 1047 km) and the Oder River (length 742 km in Poland), among which the Vistula River is called the mother river of Poland. 99.7 1% of the country belongs to the Baltic basin, of which the Vistula River basin accounts for half and the Oder River basin accounts for one third. Part of the middle and lower reaches of the Oder River is the dividing line between Germany and Poland.
The largest lake in Poland is Hinyardevi Lake, with an area of 109.7 square kilometers.
