Which structural risk increases when differential settlement occurs in a ziggurat's foundation due to variations in soil composition?

💡 Explanation

When differential settlement occurs, variations in soil compaction cause uneven loading, increasing shear stress because of the structure's rigidity, leading to cracking and potential collapse. Therefore, amplified shear stress results, rather than facade erosion, iron oxidation, or wind load effects, which depend on different environmental factors and materialproperties.
