Classify each volcanic phenomenon based on whether it is primarily associated with plate boundary interactions or intraplate mantle dynamics. Drag each answer to the correct box.

formation of batholiths through prolonged crustal thickening with limited surface eruption,episodic magma release as water-rich oceanic crust descends into the mantle,alternating explosive and effusive eruptions from variable magma composition at convergent margins|sequential emergence of volcanic islands as tectonic plates drift over stationary mantle plumes,accumulation of extensive basaltic layers from sustained mantle upwelling far from plate boundaries
