Which risk increased as Incan masonry walls became taller?

💡 Explanation

Increased height subjects the different rock types in the masonry to varying temperature gradients, resulting in differential thermal expansion stress. Therefore, taller walls increased the risk of cracking and instability, rather than pressure, friction, or weathering alone.
