← HistoryWhich outcome befell Mughal garden terracotta pipes due to sustained freezing?
A)Erosion of the brick bedding
B)Increased biofouling obstruction
C)Propagation of circumferential cracking✓
D)Dissolution of internal calcium deposits
💡 Explanation
Circumferential cracking happened because the ice crystal GROWTH mechanism caused tensile stress exceeding the terracotta's strength, rather than compression; therefore, failure initiated from tension, not from erosion or dissolution under different operating environments.
