Geography of Nepal

Geography of Nepal is uncommonly diverse. Nepal is of roughly trapezoidal shape, 800 kilometres (500 mi) long and 200 kilometres (125 mi) wide, with an area of 147,181 square kilometres (56,827 sq mi). See List of territories by size for the comparative size of Nepal.

Nepal is commonly divided into three physiographic areas: the Mountain, Hill, Siwalik region and Terai Regions. These ecological belts run east-west and are vertically intersected by Nepal's major, north to south flowing river systems.

The southern lowland Plains bordering India are part of the northern rim of the Indo-Gangetic plains. They were formed and are fed by three major rivers: the Kosi, the Narayani, and the Karnali. This region has a hot, humid climate.

The Hill Region (Pahad) abuts the mountains and varies from 1,000 to 4,000 metres (3,300–13,125 ft) in altitude. Two low mountain ranges, the Mahabharat Lekh and Shiwalik Range (also called the Churia Range) dominate the region. The hilly belt includes the Kathmandu Valley, the country's most fertile and urbanised area. Unlike the valleys called Inner Tarai (Bhitri Tarai Uptyaka), elevations above 2,500 metres (8,200 ft) are sparsely populated.

The Mountain Region, situated in the Great Himalayan Range, makes up the northern part of Nepal. It contains the regions of highest altitude in the world; the world's highest mountain, 8,850 metres (29,035 ft) height Mount Everest (Sagarmatha in Nepali) is located here on the border with Tibet. Seven other of the world's ten highest mountains are located in Nepal: Lhotse, Makalu, Cho Oyu, Kanchenjunga, Dhaulagiri, Annapurna and Manaslu.
