The Himalayas are the world's tallest mountain range, a massive system in Asia separating the Indian subcontinent from the Tibetan Plateau, home to Earth's highest peak, Mount Everest, and crucial for major Asian rivers (Ganges, Indus, Brahmaputra). Formed by tectonic collision, they boast incredible biodiversity, diverse climates from tropical to glacial, and significant cultural/spiritual importance, serving as a source of water and home to unique ecosystems and peoples.
