## Definition

the slow sinking of the ground or a building into the earth. It often happens because the soil or rock under a structure becomes weak or wet.

For teachers: the gradual sinking or settling of the earth's surface or a structure into the ground. Often caused by the erosion of underlying soil, the collapse of underground cavities, or the drying out of clay.

## Examples

- The heavy rain caused subsidence in the garden.
- Engineers are monitoring the old bridge for signs of subsidence that might compromise its structural integrity.
- Geological subsidence in the region is primarily driven by the extraction of groundwater, which leaves the underlying sediment layers unsupported and prone to gradual collapse.
