Delta

- A delta is what forms at the mouth of a river, where the water empties into a larger body of water. Sediment that is being eroded by the river builds up here and creates very rich soil.
- the fertile soil that is produced can be used for farming and crops, which makes for more food for the people.
- another benefit from the naturally rich soil is that there is plenty of plants growing, which ultimately provides more oxygen and breathable air for humans.
