Which outcome related to ziggurat stability occurs because of seasonal clay core moisture fluctuations?

💡 Explanation

When moisture fluctuates, clay cores undergo cycles of swelling and shrinking because absorbed water changes the clay volume; this induces differential settling across the structure. Therefore, uneven settling occurs, rather than effects linked to heat, salt, or root growth which operate via distinct processes.
