Which risk increased when Mesopotamian ziggurats began using mud brick fired bricks for outer layers?

A)Differential settlement cracking inner core✓

B)Seismic instability during ground movement

C)Wind erosion because outer brick layer

D)Water infiltration in the foundation

💡 Explanation

When fired bricks were used on the outside, the differential settlement became an issue because the fired bricks settled at a differing rate from the mudbrick causing stress. Therefore differential-settlement cracking increased rather than seismic instability or water infiltration because brick expands and contracts because temp.
