Where are deltas typically found?

Deltas are typically formed in regions where rivers carry sediment into larger bodies of water, such as lakes or oceans. As a river approaches its mouth, its flow velocity decreases, resulting in the deposition of sediment that has been eroded and transported along its course. This sediment builds up over time, forming a delta—a landform characterized by a fan-shaped, triangular shape, where new land is created at the interface of the river and the receiving body of water.

This process is largely influenced by the dynamics of water flow and the physical characteristics of the sediment being transported. Deltas can exhibit various forms and structures based on factors such as river discharge, sediment supply, and the energy of the receiving waters. Therefore, the correct identification of deltas being found where rivers deposit sediment into lakes or oceans reflects the fundamental processes of sediment transport and deposition in fluvial geomorphology.
