Which outcome will occur following pyroclastic surges entering floodplains?

A)Increased channel avulsion frequency downstream
B)Localized soil salinity reduction occurs
C)Rapid formation of volcanic plugs
D)Depletion of dissolved oxygen increases

💡 Explanation

Pyroclastic flows deposit debris, dramatically changing sediment supply and causing heightened aggradation; therefore, increased avulsion happens, rather than salinity changes or immediate plug formation, because avulsion matches increased floodplain sediment load changes.
