Which process limits coastal mountain chain height during subduction?

A)Erosion rates exceed uplift
B)Isostatic rebound reaches equilibrium
C)Increased sediment loading resists
D)Mantle convection cell weakening

💡 Explanation

Mountain height is limited when erosion rates exceed the tectonic uplift rate from subduction, because the increased weathering removes mass faster than it is added via crustal compression. Therefore, the height is limited by Erosional Unloading, rather than other purely tectonic factors.
