Which consequence results when extensive ashfall (tephra) buries grasslands?

💡 Explanation

Tephra deposition initially introduces minerals, but long-term vegetation smothering causes anaerobic conditions that suppresses decomposition; this causes inhibited nitrogen cycle, because of reduced microbial activity; therefore soil fertility decreases, rather than enhances plant growth.
