Which stability risk increased structurally for the ziggurat of Ur during ancient seasonal flooding?

💡 Explanation

Buoyant Uplift occurs, because infiltrating groundwater exerted upward pressure. Therefore, structural integrity weakened at the base, rather than shear from wind (minimal due to compact design) or direct thermal change (stone is a poor transmitter).
