Project Description
Nepal, officially the Federal Democratic Republic of Nepal, is a country in South Asia. It is located mainly in the Himalayas, but also includes parts of the Indo-Gangetic Plain. It is the 49th largest country by population and 93rd largest country by area. It is landlocked, and borders China in the north and India in the south, east and west, while Bangladesh is located within only 27 km (17 mi) of its southeastern tip and Bhutan is separated from it by the Indian state of Sikkim. Nepal has a diverse geography, including fertile plains, subalpine forested hills, and eight of the world’s ten tallest mountains, including Mount Everest, the highest point on Earth. Kathmandu is the capital and the largest city. Nepal is a multiethnic country with Nepali as the official language.
Nepal is of roughly trapezoidal shape, about 800 kilometres (500 mi) long and 200 kilometres (120 mi) wide, with an area of 147,181 km2 (56,827 sq mi). It lies between latitudes 26° and 31°N, and longitudes 80° and 89°E. Nepal’s defining geological processes began 75 million years ago when the Indian plate, then part of the southern supercontinent Gondwana, began a north-eastward drift caused by seafloor spreading to its south-west, and later, south and south-east. Simultaneously, the vast Tethynoceanic crust, to its northeast, began to subduct under the Eurasian plate.[63] These dual processes, driven by convection in the Earth’s mantle, both created the Indian Ocean and caused the Indian continental crust eventually to under-thrust Eurasia and to uplift the Himalayas. The rising barriers blocked the paths of rivers creating large lakes, which only broke through as late as 100,000 years ago, creating fertile valleys in the middle hills like the Kathmandu Valley. In the western region, rivers which were too strong to be hampered, cut some of the world’s deepest gorges. Immediately south of the emerging Himalayas, plate movement created a vast trough that rapidly filled with river-borne sediment and now constitutes the Indo-Gangetic Plain. Nepal lies almost completely within this collision zone, occupying the central sector of the Himalayan arc, nearly one third of the 2,400 km (1,500 mi)-long Himalayas, with a small strip of southernmost Nepal stretching into the Indo-Gangetic plain and two districts in the northwest stretching up to the Tibetan plateau.
Nepal has five climatic zones, broadly corresponding to the altitudes. The tropical and subtropical zones lie below 1,200 metres (3,900 ft), the temperate zone 1,200 to 2,400 metres (3,900 to 7,900 ft), the cold zone 2,400 to 3,600 metres (7,900 to 11,800 ft), the subarctic zone 3,600 to 4,400 metres (11,800 to 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 Himalayas block cold winds from Central Asia in the winter and form the northern limits of the monsoon wind patterns.
