Geography

The arid and barren Himalayan landscapeNepal 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, and Terai Regions. These ecological belts run east-west and are bisected by Nepal's major river systems. Nepal is roughly the same size as the US state of Michigan.
The Terai 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 (India's Gandak River), and the Karnali. This region has a hot, humid climate.
The Hill Region (Pahad in Nepali) 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, elevations above 2,500 metres (8,200 ft) are sparsely populated.
The Mountain Region contains the highest region in the world. The world's highest mountain, Mount Everest (Sagarmatha in Nepali) at 8,850 metres (29,035 ft) is located on the border with China. Eight of the world's fourteen highest mountains are located in Nepal. Kanchenjunga, the world's third highest peak, is also located in Nepal. Deforestation is a major problem in all regions, with resulting erosion and degradation of ecosystems.
Nepal has five climatic zones, broadly corresponding to altitude. The tropical and subtropical zones lie below 1,200 metres (3,940 ft), the temperate zone 1,200 to 2,400 metres (3,900–7,875 ft), the cold zone 2,400 to 3,600 metres (7,875–11,800 ft), the subarctic zone 3,600 to 4,400 metres (11,800–14,400 ft), and the arctic zone above 4,400 metres (14,400 ft). Nepal experiences five seasons: summer, monsoon, autumn, winter and spring. The Himalaya blocks cold winds from Central Asia in winter, and forms the northern limit of the monsoon wind patterns.
Although Nepal shares no boundary with Bangladesh, the two countries are separated by a narrow strip of land about 21 kilometre (13 mi) wide, called the Chicken's Neck. Efforts are underway to make this area a free-trade zone.
Mt Everest is the tallest mountain in the world, and is situated between Nepal and Tibet. The South-east ridge on the Nepalese side of the mountain is technically easier to climb, which is why so many keen climbers are pouring in through Nepal to climb Mt Everest. Also other Mountains including Annapurna I, II, III and IV are located in the Annapurna Mountain Range in Nepal.
