Belarus lies between latitudes 51° and 57° N, and longitudes 23° and 33° E. It islandlocked, relatively flat, and contains large tracts of marshy land.^[63] According to a 2005 estimate by the United Nations, 40% of Belarus is covered by forests.^[64] Many streams and 11,000 lakes are found in Belarus.^[63] Three major rivers run through the country: the Neman, the Pripyat, and the Dnieper. The Neman flows westward towards the Baltic sea and the Pripyat flows eastward to the Dnieper; the Dnieper flows southward towards the Black Sea.^[65]

The highest point is Dzyarzhynskaya Hara (Dzyarzhynsk Hill) at 345 metres (1,132 ft), and the lowest point is on the Neman River at 90 metres (295 ft).^[63] The average  elevation of Belarus is 525 feet (160 m) above sea level.^[66] The climate features cold winters, with average January temperatures at −6 °C (21.2 °F), and cool and moist summers with an average temperature of 18 °C(64

.4 °F).^[67] Belarus has an average annual rainfall of 550 to 700 mm (21.7 to 27.6 in).^[67] The country is in the transitional zone betweencontinental climates and maritime climates.

Natural resources include peat deposits, small quantities of oil and natura l gas, granite, dolomite (limestone), marl, chalk, sand, gravel, and clay.^[63] About 70%  of the radiation from neighboring Ukraine's 1986 Chernobyl nuclear disaster entered Belarusian territory, and as of 2005 about a fifth of Belarusian land (principally farmland and forests in the southeastern provinces) continues to be affected by radiation fallout.^[68] The United Nations and other agencies have aimed to reduce the level of radiation in affected areas, especially through the use of caesium binders and rapeseedcultivation, which are meant to decrease soil levels of caesium-137.^[69][70]

Belarus borders five countries—Latvia to the north, Lithuania to the northwest, Poland to the west, Russia to the north and the east, and Ukraine to the south. Treaties in 1995 and 1996 demarcated Belarus's borders with Latvia and Lithuania, but Belarus failed to ratify a 1997 treaty establishing the Belarus-Ukraine border.^[71] Belarus and Lithuania ratified final border demarcation documents in February 2007.^[72]
