How Mountains Are Made

Earth’s landscape is a masterpiece millions of years in the making, driven by the restless process of orogenesis, or mountain building. While the Earth’s temperature rises by an average of 20 to 30 degrees Celsius for every kilometer you go deeper into the continental crust, heat alone isn't enough to melt the planet. Under normal conditions, the immense pressure at great depths keeps rocks solid, preventing the temperature from reaching the "solidus" line required for melting. The real magic happens at subduction zones, where one plate is forced beneath another. As the subducting plate sinks, it begins to "sweat" water into the surrounding mantle. This water acts as a secret ingredient that drastically lowers the melting point of the rock, creating a "wet melting curve". This allows magma to form and rise, fueling the volcanic arcs that often accompany mountain ranges. In Europe, these tectonic collisions have shaped the continent through three major episodes. It began with the ancient Caledonian orogeny, followed by the Hercynian period which laid the foundations of Central Europe, and finally the Alpine orogeny, which created the jagged peaks of the Alps we see today. Throughout these eras, forces of compression and tension have buckled the crust into folds and fractures, constantly recycling the Earth's surface and proving that our planet is a dynamic, living system.
