← GeographyWhich outcome arises when volcanic ash deposition disrupts pedogenesis?
A)Accelerated chemical weathering
B)Formation of andisols✓
C)Decreased soil porosity
D)Stabilized organic matter content
💡 Explanation
Andisol formation occurs because significant volcanic ash input rapidly alters soil composition; therefore the distinct andic properties form, rather than the typical gradual horizon development associated with other forms of pedogenesis.
