The Himalayas or Himalaya is a mountain range in the Indian subcontinent, which separates the Indo-Gangetic Plain from the Tibetan Plateau. The Himalayan range runs northwest to southeast in a 2,400-kilometre (1,500 mi)-long arc. The range varies in width from 400 kilometres (250 mi) in the west to 150 kilometres (93 mi) in the east. Other than the Greater Himalayas, there are several parallel lower ranges. The total area of Himalayas is 1.089 million km² which includes nine of the ten highest peaks on Earth. The highest peak is the Mount Everest at 29,029 ft (8,848 m) ,the highest on the entire planet.
The Himalayas are one of the youngest mountain ranges on the planet formed as an impact of the Indian tectonic plate. This travels northward at 15 cm per year, and joined the Eurasian continent about 40-50 million years ago. The formation of the Himalayas resulted in the lighter rock of the seabeds of that time being lifted up into mountains. The Indian plate still moves north at 67 mm per year rising the Himalayas by about 5 mm per year, making them geologically active. The movement also leads to earthquakes from time to time.
The five main rivers of the Himalayas are the Jhelum, Chenab, Ravi, Beas, and Satluj. The rivers are the main source of human and animal life in those areas. The Himalayas are very popular for tourists because it has a lot of wildlife, plants and trees.
