Which outcome resulted from thermal cycling affecting Egyptian limestone?

💡 Explanation

Block spalling occurred in limestone because repeated heating and cooling causes THERMAL EXPANSION AND CONTRACTION. Micro-cracks propagate due to anisotropic expansion, splitting the stone, therefore promoting surface failure rather than bulk changes by chemical weathering or plastic flow.
