The 62-kilometre-long Baltoro Glacier, in northern Pakistan, is one of the longest glaciers outside the polar regions
Geologically, Pakistan overlaps with the Indian tectonic plate in its Sindh and Punjab provinces, while Balochistan and most of Khyber Pakhtunkhwa lie within the Eurasian plate which mainly comprises the Iranian plateau. Gilgit-Baltistan and Azad Kashmir lie mainly in Central Asia along the edge of the Indian plate and are hence prone to violent earthquakes.
The geography of Pakistan is a blend of landscapes varying from plains to deserts, forests, hills, and plateaus ranging from the coastal areas of the Arabian Sea in the south to the mountains of the Karakoram range in the north. Pakistan is divided into three major geographic areas: the northern highlands; the Indus River plain; and the Balochistan Plateau.[84] The northern highlands of Pakistan contain the Karakoram, Hindu Kush and Pamir mountain ranges, which incorporate some of the world's highest peaks, including K2 (8,611 m or 28,251 ft) and Nanga Parbat (8,126 m or 26,660 ft). The Balochistan Plateau lies to the West, and the Thar Desert in the East. An expanse of alluvial plains lies in Punjab and Sindh along the Indus river. The 1,609 km (1,000 mi) Indus River and its tributaries flow through the country from the Kashmir region to the Arabian Sea.[85]
Main article: Climate of Pakistan
Pakistan's climate varies from tropical to temperate with arid conditions existing in the coastal south, characterised by a monsoon season with frequent flooding rainfall and a dry season with significantly lesser to no rainfall. There are four distinct seasons; a cool, dry winter from December through February; a hot, dry spring from March through May; the summer rainy season or southwest monsoon period, from June through September; and the retreating monsoon period of October and November.[86] Rainfall can vary radically from year to year, and successive patterns of flooding and drought are common.[87]
