Which outcome primarily results from water being dragged down by a subducting oceanic plate?

💡 Explanation

When water is dragged down during subduction, flux melting occurs due to the lowered melting point of the mantle rocks from the added water, generating magma that rises to form volcanoes. Therefore volcanoes result, rather than decreasing heat flow, accelerated spreading, or transform faults which are caused by different tectonic stresses.
