← HistoryWhich long-term weathering risk accelerates in the pietra dura inlay present on large Mughal-era structures?
A)Differential thermal expansion✓
B)Uniform corrosion resistance
C)Homogeneous material degradation
D)Integral structural reinforcement
💡 Explanation
Differential thermal expansion degrades pietra dura because varying coefficients cause stress fractures, therefore inlays detach rather than remaining intact, because rates of expansion in stone/inlay differ under changing temperatures.
