← GeographyWhich outcome occurs when shield volcanoes overly a hotspot?
A)Chains of islands formation✓
B)Formation of rift valley systems
C)Increased frequency of pyroclastic flows
D)Caldera collapse due to magma depletion
💡 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.
