Which process causes rapid uplift on the footwall side adjacent to normal fault during extension?

A)Elastic rebound from locked fault
B)Isostatic rebound from erosion unloading
C)Flexural isostasy from sediment deposition
D)Erosion via headward stream capture

💡 Explanation

When a normal fault is locked, elastic strain accumulates. Once the fault ruptures, elastic rebound mechanism occurs because stored energy is released, causing rapid uplift on the footwall. Therefore elastic rebound results, rather than other isostatic mechanisms which operate on longer timescales under different conditions.
