Which outcome occurs when construction on unstable alluvial terraces?

💡 Explanation

Construction destabilizes the already compressible material experiencing differential consolidation because increasing the load of a structure causes faster settling. Ground settles unevenly eroding the building’s underpinnings; therefore subsidence occurs on floodplains, rather than heightened wind risk.
