← GeographyWhich outcome occurs when Mount St. Helens' lateral blast deposits ash?
A)Plant community ecological succession restarts.✓
B)Glacial ice accumulation rates accelerate.
C)Regional albedo indices immediately decrease.
D)Deep soil horizons receive new nutrients.
💡 Explanation
Ecological succession restarts because pyroclastic flows sterilize land. This initiates primary succession, rather than accelerating glacier growth, changing albedo indices broadly, or deeply enriching soil, because those rely on distinct influences rather than near-total organic destruction.
