The story of mountains—the slow processes of erosion and uplift, of tectonic drift and aeolian deposition—is, in its own way, a fundamental facet of the story of human civilization. In India, the annual monsoon is caused, in part, by the presence of the Himalayas; shifts in the monsoon helped bring down one of the Earth's first great civilizations. Hannibal's conquest of the Alps, in the 200s B.C., is a celebrated facet of military history. Even in the U.S., an infant nation on geological timescales, mountains affect where we live (coastal California), and where we don't (Death Valley).
Doran's video focuses on processes: how the sun and wind and rain affect a mountain's face. For Minute Earth, Henry Reich and team answers a more specific, related question: "How Tall Can Mountains Be?"
