Which geologic outcome results from repeated rupture along a transform fault boundary located beneath a shallow ocean?

A)Formation of spreading volcanic islands
B)Development of submarine canyons
C)Accretion of uplifted oceanic plateaus
D)Creation of offset stream drainage patterns

💡 Explanation

When repeated rupture events happen along a shallow, submerged transform fault, strike-slip motion occurs because shear stress accumulates and releases as earthquakes, offsetting pre-existing stream channels flowing into the fault zone. Therefore, offset drainage patterns result, rather than volcanism, canyons, or plateau accretion which depend on other tectonic processes.
