Geology of North America: Mountain Building

The video discusses the major mountain systems in North America, including the Appalachian, Rocky, and Pacific Mountain systems. It explains the process of mountain building, known as erogeny, and highlights the tectonic activities that have shaped these mountains. The video also covers the volcanic activity in the Cascades and the formation of the Sierra Nevada range. It concludes with a reminder of the ongoing geological research in mountain building.
