← GeographyWhich mechanism causes coastal uplift where a reverse fault system experiences repeated rupture events,?
A)Flexural isostasy via mantle convection
B)Elastic rebound through fault creep
C)Brittle deformation accumulating displacement✓
D)Dynamic subsidence from sediment loading
💡 Explanation
When reverse faulting occurs, compressional force causes differential displacement, accumulating with each rupture event, because brittle deformation results in blocks of crust sliding past each other leading to crustal thickening. Therefore coastal uplift results, rather than isostasy, which relies on density changes; creep, a slower continuous movement; or subsidence, a sinking motion.
