Question
Occurs when there is loss of support below ground
Answers

The phenomenon you are describing sounds like "ground subsidence." Ground subsidence occurs when there is a loss of support beneath the ground surface, leading to a downward sinking or settling of the land. This can result from various factors, including:
1. **Soil Compaction**: Over time, certain types of soil (like clay) can become compacted, causing the ground above them to sink.
2. **Mining Activities**: The removal of minerals or resources underground can leave voids that cause the surface to collapse.
3. **Withdrawal of Groundwater**: Excessive extraction of groundwater can lead to a decrease in water pressure in the soil and rock layers, resulting in subsidence.
4. **Natural Processes**: The natural settling of sediments over time or the dissolution of limestone (creating sinkholes) can also cause ground subsidence.
5. **Construction and Structural Changes**: Heavy infrastructure or improper construction practices can lead to loss of support for the ground above it.
