Submerged settlements are communities or cities that have been partially or completely covered by water, often due to rising sea levels, flooding, or the construction of dams. These areas can provide valuable insights into past human activities, architecture, and environmental changes. Archaeologists study submerged settlements to learn about ancient cultures and their adaptations to changing landscapes. Examples of submerged settlements include the ancient city of Dwarka in India and Yonaguni in Japan. These sites often attract divers and researchers, as they hold artifacts and structures that can reveal information about historical civilizations and their interactions with the environment.
