← GeographyWhich process causes uplift along a reverse fault boundary undergoing compression?
A)Isostatic rebound from erosion unloading
B)Elastic strain accumulation exceeding friction✓
C)Thermal expansion due to magma intrusion
D)Sediment deposition loading the crust
💡 Explanation
When compressive forces act on a reverse fault, elastic strain accumulates because friction prevents immediate slippage, eventually exceeding frictional strength where the hanging wall thrusts upwards. Therefore uplift occurs, rather than isostatic rebound, thermal expansion, or sediment loading, which involve unrelated geological mechanisms.
