History

Which consequence resulted when ancient Cusco's fit with clay mortar failed?

A)Stone shifted during seismic events
B)Canals experienced cascading water failures
C)Quipu records became irreversibly unreadable
D)Terracing crops led to nutritional deficiency

💡 Explanation

Seismic events induce inertial forces, thereby causing stone motion and the dissipation of kinetic/potential energy. Since clay mortar had no reinforcement that could be present to resist sheer forces in earthquakes, stones settled unevenly rather than uniformly.
