Ancient River Delta

An ancient river delta is a landform created where a river flows into a larger body of water, depositing sediment such as sand, silt, and clay over time. These deposits build up and spread out in a fan-shaped pattern, forming rich, fertile land that can support diverse ecosystems and human activity. Over thousands or millions of years, these deltas can become buried and preserved as part of the geological record, providing valuable insights into past environments, climate, and sedimentation processes. Examples include the Nile Delta and the Mississippi River Delta.
