Which environmental consequence results when extensive tephra deposition occurs?

💡 Explanation

Extensive tephra deposition leads to long-term decline in soil productivity because the mechanism of nutrient depletion introduces high acidity; therefore, land productivity decreases rather than enhancement as soluble minerals leach out.
