Which feature forms when a continental plate overrides an oceanic plate with high volatile content?

💡 Explanation

When a continental plate overrides an oceanic plate, volatile-rich components lower the mantle's melting point through flux melting, initiating magma formation which leads to volcanism that creates a coastal volcanic arc. Therefore, coastal arcs form, rather than island arcs, rift valleys, or fold mountains, which result from different tectonic and volatile conditions.
