Which risk increases when differential settling compromises the mudbrick core of a ziggurat?

💡 Explanation

When differential settling occurs, the varied consolidation of the subsoil beneath different sections induces stress risers in the mudbrick core because the material has low tensile strength, causing leaning. Therefore accelerated leaning results, rather than changes in heating, moat performance, or observation disruption, tied to temperature, water flow, or sightline impairments respectively.
