The major mountain range that runs along the northern border of the Indian subcontinent is the Himalayas. This formidable range is home to some of the world's highest peaks, including Mount Everest, which stands at 8,848 meters above sea level. The Himalayas have significant cultural, ecological, and climatic importance, influencing weather patterns across the region and serving as a natural barrier. Additionally, they are crucial to local communities, providing resources and supporting diverse ecosystems unique to high-altitude environments.
