← HistoryWithin Mughal gardens, which outcome accelerates water feature degradation due to capillary action?
A)Salt crystallization within porous sandstone✓
B)Algae's photosynthetic pH level alteration
C)Erosion by rapid water drainage
D)Thermal stresses on marble surfaces
💡 Explanation
Salt crystallization causes sandstone crumbling because water carries dissolved salts into the stone, where evaporation results in crystallization, exerting pressure which fractures the pore spaces. Thus, salt crystal growth degrades sandstone features, rather than thermal stress affecting marble.
