Which outcome arises when Inca terracing destabilizes slopes?

💡 Explanation

Rotational landslides occur because *increased soil saturation* reduces shear strength within the terrace fill, therefore overall slope stability declines triggering slides, rather than just surface erosion or altered soil chemistry.
