Final answer:
Land subsidence is likely whenever groundwater is used nonrenewably from aquifers composed of sediment.
Step-by-step explanation:
Land subsidence is likely whenever groundwater is used nonrenewably from aquifers composed of sediment. When groundwater is withdrawn from aquifers composed of sediment, the void spaces previously filled with water are emptied, causing the sediments to compact and the land above to sink. This subsidence can result in significant damage to infrastructure and ecosystems.
