what boundary is at the himalayan mountains
The Himalayan range is bordered on the northwest by the Karakoram and Hindu Kush ranges, on the north by the Tibetan Plateau, and on the south by the Indo-Gangetic Plain. The Himalayas are distinct from the other great ranges of central Asia, although sometimes the term Himalaya is loosely used to include the Karakoram and some of the other ranges.
