Within Mughal gardens using pietra dura, which consequence results from excessive water evaporation?

💡 Explanation

Excessive evaporation drives mineral salt deposition onto porous material because capillary action pulls dissolved solids to the surface causing efflorescence. Therefore, surface staining increases, rather than directly causing gemstone changes or structural issues; hydraulic pressure is also not relevant.
