Which outcome accelerates sediment deposition in fault-block basins?

A)Isostatic subsidence increases accommodation space
B)Increased erosion minimizes sediment yield
C)Decreased fault activity reduces tilting
D)Uplifted watersheds stabilize against incision

💡 Explanation

Isostatic subsidence increases accommodation space because the crust sinks under the sediment load along the fault, creating more room; therefore, rapid deposition occurs rather than inhibited deposition from stable crust.
