What physical feature blocks access to the Indian subcontinent to its north and north east

Answer 1

The physical feature that blocks access to the Indian subcontinent to its north and northeast is the Himalayas. This mountain range includes some of the highest peaks in the world, including Mount Everest, and serves as a natural barrier separating the Indian subcontinent from the regions of Tibet and Central Asia. Additionally, the northeastern part of India is bordered by hills and mountain ranges such as the Patkai and the Eastern Himalayas, which create difficult terrain and further limit accessibility.
