← GeographyWhich outcome is driven by flux melting at subduction zones?
A)Formation of volcanic island arcs✓
B)Development of transform fault lines
C)Creation of mid-ocean ridge systems
D)Generation of deep ocean trenches
💡 Explanation
Volcanic island arcs form due to flux melting, lowering the mantle's melting point with water, because volatiles are introduced from a subducting plate. Therefore, magma is generated, which erupts at the surface as volcanoes rather than causing oceanic trenches.
