Which mechanical effect arises when early aqueducts utilizing soft sedimentary rock undergo substantial freeze-thaw cycles?

💡 Explanation

The channel accelerates collapse due to frost wedging; water expands upon freezing within the stones' pores, exerting outward pressure. Because that expansion fractures material further, therefore weakening the entire aqueduct, rather than facilitating sturdier features against water pressures.
