Which topographic effect results when shield volcanoes overly lithospheric hotspots?

💡 Explanation

Progressive island chains form due to plate movement over fixed mantle plumes. Continuous volcanism builds above sea level because the overriding plate transports active volcanoes away from the hotspot, therefore new volcanoes form rather than continuously building one massive landmass.
