Which outcome occurs when mantle plumes induce melting?

A)Intraplate hotspot volcanism forms
B)Subduction zone volcanism ends
C)Transform fault earthquakes decrease
D)Continental crust accretion decelerates

💡 Explanation

Intraplate hotspot volcanism occurs due to decompression melting from mantle plumes creating pathways, because these plumes rise independently of plate boundaries and cause volcanism in plate interiors. Surface volcanism manifests where plumes intersect the lithosphere, therefore they create hot spots rather than zones, because hotspots don't generate earthquakes like faults.
