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).
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 or Terai bordering India are part of the northern rim of the Indo-Gangetic plains. They were formed and are fed by three major Himalayan rivers: the Kosi, the Narayani, and the Karnali as well as smaller rivers rising below the permanent snowline. This region has a subtropical to tropical climate. The outermost range of foothills called Shiwalik or Churia Range cresting at 700 to 1,000 meters marks the limit of the Gangetic Plain, however broad, low valleys called Inner Tarai (Bhitri Tarai Uptyaka) lie north of these foothills in several places.
