← GeographyWhich phenomenon primarily drives the formation of linear valleys along oceanic transform faults?
A)Thermal expansion of newly formed crust
B)Erosion concentrated by sheared rock✓
C)Deposition suppressed by fault movement
D)Subduction inducing regional subsidence
💡 Explanation
When plates slide laterally along transform faults, shearing causes intense fracturing and brecciation of the rock, making it exceptionally vulnerable to erosion by currents and turbidity flows. Therefore concentrated erosion results, rather than expansion, suppression, or subsidence which are driven by different tectonic processes.
