← GeographyWhich effect arises from differing velocities along a transform fault boundary?
A)Formation of fault gouge and breccia✓
B)Stratovolcano formation through crustal melting
C)Abyssal plain development via sediment deposition
D)Rift valley creation due to crustal extension
💡 Explanation
When plates move at varying speeds along a transform boundary, intense frictional forces abrade and pulverize the rock because the irregular surfaces grind together. This creates fault gouge and breccia. Therefore, a results, rather than volcanos, abyssal plains, or rift valleys, which involve different tectonic plate dynamics.
