Question

How is a delta created

Answer 1

The delta is created by the accumulation of material from the river at the end of its flow.

Explanation:

The delta is a physical feature that is formed by the influence of the water, or more specifically by the rivers. Basically, as the river comes to the end of its flow, or better said entering another, larger, water body, it slows down significantly. Because it slows down, it loses its velocity, which in turn means that it can no longer carry the majority of the material it has been carrying to there.

The material gets deposited. As more and more material is deposited, it piles up, creating a sandy land form. The deposited material gradually starts to block parts of the river, so the river starts to branch out in order to continue its flow to the larger water body. The end result is a triangular, sandy physical feature, cut through by numerous smaller ''sleeves'' of the river.

Some of the largest deltas in the world are:

• Ganges delta
• Nile River delta
• Amazon delta
• Mississippi delta
• Mekong delta
• Niger delta
• Danube delta
