Which mechanism contributed to ziggurat settlement instability when built on clay plains?

💡 Explanation

Differential subsurface consolidation caused subsidence due to uneven loading on the foundation material. The clay swelled or compacted under different sections of ziggurat because load varied across structure, therefore the outcome was instability rather than uniform settling or displacement due external factors.
