Which erosional pattern is prominently formed through subduction-related volcanic arc activity?

💡 Explanation

When subduction occurs beneath continental crust, composite volcanoes form due to high silica content magma, creating steep slopes where the lava flows radially downwards leading to radial drainage patterns. Therefore radial drainage is more typical, but dendritic drainage and trellis drainage pattern formation requires other geologic conditions, rather than subduction volcanoes.
