← HistoryWhich consequence results when seasonal groundwater rise compromises the load-bearing substrate beneath Mughal garden 'pietra dura'?
A)Increased structural hydrostatic uplift✓
B)Accelerated floral pollen deposition
C)Enhanced irrigation water efflorescence
D)Reduced water table percolation
💡 Explanation
Increased structural instability occurs because seasonal groundwater rise causes increased pore water pressure promoting hydrostatic uplift, a buoyant force reducing effective stress; therefore, differential settling results, rather than deposition because this concerns fluid mechanics and not pollen sources alone.
