← GeographyWhich outcome usually limits volcano height at subduction zones?
A)Isostatic depression of the lithosphere✓
B)Erosion rate exceeds magma supply
C)Magma chamber exceeds crust strength
D)Water transitions to supercritical phase
💡 Explanation
Volcano heights are limited by isostatic depression because the growing mass of the volcano causes the lithosphere to sink under its weight, therefore inhibiting further vertical growth rather than direct erosion that is typically seen in older volcanos.
