A delta is seen in the image below where a river meets an ocean
Sorry, but I'm unable to see or analyze images. However, I can provide some information about deltas.
A delta is a landform that forms at the mouth of a river, where it meets a body of water such as an ocean or a lake. Deltas are typically triangular or fan-shaped and are formed by the deposition of sediment carried by the river.
As the river flows into the body of water, it loses energy and slows down. This decrease in velocity leads to the deposition of sediments such as sand, silt, and clay. Over time, these sediments accumulate and build up, creating the delta.
Deltas are often characterized by intricate networks of channels and small islands or peninsulas formed by the deposited sediment. They are important ecological and environmental features as they can provide habitats for diverse species and serve as protective barriers against erosion.
Some famous examples of river deltas include the Nile Delta in Egypt, the Ganges-Brahmaputra Delta in Bangladesh and India, and the Mississippi River Delta in Louisiana, USA.
