The 'Patkai Bum' hills, which form a part of Purvanchal mountain range along the eastern border of India, are situated primarily in which region?

💡 Solution & Explanation

The Patkai Bum hills form a prominent section of the Purvanchal mountain chain situated along India's international boundary with Myanmar in the northeastern sector. These rugged ranges traverse parts of Arunachal Pradesh and Nagaland, acting as a natural climatic and cultural barrier between the Brahmaputra valley and Southeast Asia. Other ranges in the Purvanchal system include the Naga Hills, Manipur Hills, and the Mizo Hills. Dense tropical evergreen forests and steep ridges characterize the geomorphology of this remote mountainous terrain.
