At the Great Zimbabwe enclosure, which consequence originates from thermal expansion in the stone masonry?

💡 Explanation

Repeated heating and cooling cycles induce thermal expansion; differential expansion causes internal stresses exceeding the material's cohesive strength, resulting in crack propagation and decreased structural integrity because masonry experiences volumetric changes. Therefore the wall becomes less stable, rather than remaining stable due to thermal adaptation.
