After rapid tephra deposition from Plinian eruptions, which outcome diminishes slope erodibility?

💡 Explanation

Increased soil aggregate stabilization reduces erosion because clay particles bind tephra through electrostatic attraction, forming larger, more resistant clumps. Therefore, option A is correct rather than increased runoff or pore water pressure because the tephra stabilizes via aggregation.

• Which mechanism causes increased salinity in closed-basin lakes in arid climates experiencing long-term drought?
• Which outcome occurs when enhanced radiative forcing destabilizes Hadley cells?
• Which soil outcome increases alongside accelerated glacial retreat?
• Which mechanism strengthens gyre formation when Hadley cells intensify?
• Which volcanic outcome results when a confined eruption transitions directly from a lava dome collapse to intense pyroclastic flow?
