Physiographic Province: A large geographical region characterized by a distinct combination of landforms and geological history.
Tectonic Plate Convergence: The process where two or more of Earth's tectonic plates move towards each other, often resulting in mountain building or volcanic activity.
Volcanic Arc: A curved chain of volcanoes produced by the subduction of one tectonic plate beneath another.
