Which outcome results when a mosaic's tesserae, securing to an aged Byzantine church's ceiling, experience delamination?

💡 Explanation

Falling tesserae constitute a mosaic's degradation precisely which cause spalling. Because adhesive failure occurs despite gravity, this mechanical action causes debris falling, therefore localized areas will fall rather than structural instability, enhanced acoustics, or changed building thermodynamics.
