Which mechanism is most dominant immediately inland from an oceanic-continental subduction zone?

💡 Explanation

When an oceanic plate subducts, dehydration of the slab and mantle wedge melting occurs because water lowers the melting temperature, generating buoyant magma that ascends and causes magmatic crustal addition at volcanic arcs. Therefore magmatic addition is dominant, rather than modes like strike-slip faulting or isostatic rebound away from plate boundaries.
