← HistoryWhich risk increases when ziggurat drainage channels clog?
A)Decreased structural shear resistance
B)Accelerated facade salt weathering✓
C)Insufficient mud-brick production
D)Compromised cult statue placement
💡 Explanation
Clogged channels prevent rainwater runoff managing salts dissolved in the mud-brick; capillary action causes salt crystallization due to evaporative CONCENTRATION weakening the facade of the Ziggurat, because salts expand. Therefore accelerated weathering, rather than structural issues, becomes the dominant failure mode.
