Answer:
There is a gradual decline of volcanic age form the continental to the oceanic. As some of the volcanoes get eroded away.
Explanation:
- The hotspot volcanoes are transported by plate movements as they move away form the mantel plumes the hotspot volcanism decreases. Then eventually the hotspots become extinct.
- Thus on the basis of age the youngest are near the places active tectonism where the magma is directly ground underneath the ground surface.
