← GeographyWhich process explains crustal thickening at convergent boundaries?
A)Episodic tremor and slip (ETS)✓
B)Strike-slip fault propagation
C)Intraplate volcanism hotspot track
D)Oceanic fracture zone development
💡 Explanation
Episodic tremor and slip (ETS) generates slow-slip earthquakes at subduction zones because aseismic slip accommodates strain, leading to crustal thickening and uplift, therefore thickening occurs, rather than sudden ruptures along locked faults.
