Which consequence results from long-term seasonal water table fluctuations around a ziggurat's mud-brick foundation?

💡 Explanation

When seasonal water tables fluctuate, repeated wetting and drying under the foundation induce consolidation and swelling of clay-rich soils creating heaving, differential settling, causing stresses on the entire structure. Therefore, structural cracking occurs, rather than sulfate attack, infestation or heat flux changes with require chemically or biologically induced degradation.
