Details
The Himalayas comprise three distinct parallel ranges: the Greater Himalayas with perennial snow, the Lesser Himalayas with temperate forests, and the Outer Siwalik Hills. This vast system creates diverse ecosystems from subtropical valleys to alpine meadows, supporting unique flora and fauna including snow leopards, red pandas, and Himalayan tahrs. Culturally, the region holds immense spiritual significance for Hindus and Buddhists, with sacred peaks like Kailash and pilgrimage sites dotting the valleys. The mountains act as a rain shadow barrier, forcing monsoon winds to release moisture on their southern slopes, creating India's lush agricultural zones while leaving the north rain-deficient. Glacial melt from the Himalayas sustains billions of people across South and Southeast Asia through perennial river systems.
