← HistoryWhich consequence results when breached Mesopotamian canal walls experience capillary action?
A)Increased hydrostatic uplift pressure
B)Decreased soil shear strength
C)Accelerated salt mineral crystallization✓
D)Diminished evaporative cooling effects
💡 Explanation
Accelerated salt mineral crystallization results, because capillary action draws saline groundwater into the wall. This causes water to evaporate, leaving behind dissolved salts that crystallize and expand. Salt crystal growth weakens the wall internally, rather than hydrostatic pressure increases.
