← HistoryWithin siege warfare during the Byzantine empire, which outcome occurs, under sustained Greek fire bombardment of stone city walls?
A)Localized wall spalling increases rapidly✓
B)Unstable footing accelerates subsidence
C)Complete combustion removes structural supports
D)Toxic fumes incapacitate garrison defenders
💡 Explanation
Localized spalling of the stone material grows rapidly because the intense heat from Greek fire causes differential thermal expansion within the stone leading to cracking and fragment ejection, a mechanism called thermal shock. Therefore, spalling increases rather than combustion or subsidence as stone does not sustain those consequences
