The major mountain range found in the northern part of India is the Himalayas. This range includes some of the highest peaks in the world, including Mount Everest and Kanchenjunga. The Himalayas are crucial for India's climate, as they act as a barrier to cold winds from Central Asia, leading to warmer temperatures in the Indian plains. The region is also rich in biodiversity and cultural heritage, serving as home to various ethnic groups, languages, and traditions.
