Which outcome occurs when shield volcanoes overly a hotspot?

💡 Explanation

Island chains form due to plate movement over a stationary hotspot that causes repeated volcanic activity; this is volcanism related to plume tectonics. Island formation occurs because of magma generation, therefore ocean island chains appear, rather than rifts or increased pyroclastic activity at only one volcano.
