← GeographyWhich ecosystem change results when sequential pyroclastic flows deposit stratified materials atop one another?
A)Reduction in slope stability triggers landslides
B)Formation of mineral-rich soil horizons✓
C)Diminished atmospheric ozone concentrations globally
D)Increased regional precipitation intensities
💡 Explanation
Stratified pyroclastic material undergoes differential weathering via chemical alteration, causing varying mineral concentrations. This creates favorable conditions for specialized plant colonization that enriches the weathered substrate as the soil horizons form, thereby increasing mineral-rich soil rather than triggering landslides or other atmospheric effects.
