Which risk increases when facing stones with sedimentary layering for load-bearing courses during Inca building projects?

💡 Explanation

Reduced load capacity risk rises because 'Shear Failure' mechanism occurs more easily along bedding planes, therefore structural integrity degrades rather than remaining competent like homogenous igneous rocks under compression.
