Our system will evaluate the answer based on this AI-generated description.
The image features a diagram titled "How is a delta formed?" presenting a three-step sequential process labeled with numbered points 1 to 3. Step 1 displays a river flowing between landmasses into a large body of water, accompanied by the text: "1 Velocity slows dramatically when a river meets a large body of water." Step 2 illustrates sediment fragments appearing at the mouth of the river entering the water, labeled: "2 Because of the decrease in velocity, sediments are deposited." Step 3 shows an extensive network of branching sediment channels extending into the water body, labeled: "3 Over time, the sediments build up, forming a delta."
Given the complexity of the image, the above description may not be entirely accurate.

The diagram provides information about the natural process by which developing a river delta, from transportation of residues or sediments to the formation into network channels at the river mouth.
Overall, the river delta is gradually natural process involving three main stages. Originally, a river carries sediment downward to the sea. This process makes a river delta with depositing and accumulating the sediments, creating a river delta.
At the beginning velocity slows dramatically when a river meets a large body of water, eroding rocks of mountains and sediments, dividing into smaller channels. As a result, sediment consisting of sand, silt and clay is carried downstream of the moving the water.
During the significant stages, the destroyed materials gradually accumulates, building up new land around the river mouth. As this process continues, the main river divides into small brabches. Eventually, the sediments build up a river delta, at the ending of the stage.
