← HistoryWhich outcome occurs when uneven settling affects a ziggurat?
A)Increased shear stress on mudbrick✓
B)Water infiltration accelerates clay expansion
C)Erosion decreases base structural support
D)Internal cooling exceeds radiative warming
💡 Explanation
Increased shear stress occurs because differential settlement introduces stresses exceeding the mudbrick's elastic limit, leading to cracking via stress concentration, therefore structural integrity decreases rather than uniform settling because mudbrick lacks tensile strength relative to compressive loads.
