← GeographyWhich effect is directly caused by the stick-slip mechanism along transform plate boundaries?
A)Lithospheric mantle hydration
B)Episodic seismic moment release✓
C)Formation of island arc volcanoes
D)Propagation of deep mantle plumes
💡 Explanation
When tectonic plates move along a transform boundary, the stick-slip mechanism causes stress to accumulate as the plates lock, then suddenly release as they slip, generating earthquakes. Therefore episodic seismic moment release results because frictional resistance fluctuates, rather than hydration, volcanoes, or plumes that require different geological settings and processes.
