The Himalayas, also known as the Himalaya, is a mountain range in Asia separating the Indian subcontinent from the Tibetan Plateau. The range has many of Earth’s highest peaks, including the highest, Mount Everest. The Himalayas include over fifty mountains exceeding 7,200 m (23,600 ft) in elevation, including ten summits exceeding 8,000 m (26,247 ft). By contrast, the highest peak outside Asia – Aconcagua in the Andes – is 6,961 m (22,838 ft).
The Himalayan range is bordered on the northwest by Pakistan’s Northern Areas and Gilgit-Baltistan region; to the northeast by India’s state of Sikkim and east of Nepal; and to the southeast by Bhutan. To the south lies Bangladesh. Most of Nepal and Bhutan are located within it. Myanmar lies to its east. It contains twenty-nine peaks that are each more than 7200m above sea level: eighteen in Tibet Autonomous Region of China including Mount Everest; six in Nepal including Makalu and Lhotse; four in India including Kanchenjunga; one in Pakistan Nanga Parbat.
The Hindu Kush range extends between central Afghanistan and northern Pakistan roughly along a southwest-to-northeast axis at an average elevation around 4200m. Including all subsidiary ranges like Sivalik Hills or Pir Panjal Range it covers almost entire length of Afghan-Pakistani border which is about 2400km. The Hindu Kush system includes several lower mountain ranges like Sulaiman Mountains with an average height around 3000m which stretch along Pakistani provinces of Khyber Pakhtunkhwa and Balochistan towards Iranian border while others are even lower like Kirthar Mountains with an average elevation around 1000m which run along Pakistani province of Sindh towards eastern border with India where they join Aravali Range forming world’s oldest mountain system called Indian Shield covering almost entire Rajasthan state up to Delhi National Capital Territory.”
