Which outcome arises when water freezes inside cracks within ancient stone aqueducts?

💡 Explanation

When water freezes, ice expansion within the confined space of a crack generates significant pressure via the frost wedging mechanism, exceeding the tensile strength of the rock causing fracture. Therefore, accelerated structural fracture results, rather than mineral deposition, reduced flow, or biological growth which require different environmental conditions.
