The Longest Mountain Ranges

This episode explores the world’s longest mountain chains, beginning with the Andes, the longest continental mountain range on Earth, and continuing through the Rockies, the Urals, the Atlas Mountains, and the vast mountain systems of Central Asia, including the Himalayas, Karakoram, and Hindu Kush. It explains how tectonic plate collisions, uplift, erosion, and glaciers shaped these immense landscapes over millions of years. The episode also highlights how mountain ranges influence climate, river systems, biodiversity, and human civilization by acting as barriers, water sources, and routes of cultural exchange. Ultimately, it shows that the world’s great mountain ranges are not only spectacular landforms, but powerful forces that shape continents, ecosystems, and human history.
