The Dangers and Causes of Sinkholes
TLDR Sinkholes, which are formed when water erodes the bedrock beneath the soil, can be caused by various factors including spalling, cover subsidence, dissolution, and human activities such as drilling and mining. They can result in widespread destruction and can be a result of natural processes or human actions.
