Which environmental risk challenged Roman aqueduct design when traversing areas with limestone bedrock?

💡 Explanation

When aqueducts passed over limestone, dissolution and structural weakening occurred due to the water dissolving the calcium carbonate bedrock, creating voids altering the hydraulic properties compromising integrity. Therefore dissolution results, rather than thermal, seismic, or biological effects requiring different environmental preconditions and mechanisms.
