Arc continent mountain formation typically involves several key steps: First, the subduction of an oceanic plate beneath a continental plate occurs, leading to the melting of the oceanic crust and the formation of magma. This magma rises to the surface, resulting in volcanic activity that forms an island arc. Over time, tectonic forces cause the colliding plates to fold and uplift the continental crust, creating mountain ranges. Erosion and sedimentation further shape these mountains, resulting in the complex topography we see today.
