Major Mountain Ranges in India

1. The Himalayas

• The Himalayas are one of the major mountain ranges of the world.

• The approximate length of the Himalayas is 2,500 km from east to west, and their width varies between 160-400 km from north to south.
• They are spread across 5 countries: India, Nepal, Bhutan, China, and Pakistan.
• The Himalayas are further divided into three sub-ranges (North to South):
