Which failure mode accelerated the degradation of stone aqueducts?

💡 Explanation

Repeated freezing and thawing caused frost wedging within the porous stones, because the expansion of ice exerted pressure exceeding the stone's tensile strength, therefore the aqueduct weakened and cracked, rather than remaining stable under compression or erosion.
