A delta the size of the Mississippi River will take several thousand of years to form because the process of formation of a delta is geologically controlled.
A delta is a place where river enters or drains into the sea with many mouth or outlets.
Deltas are depositional terrain full of dis-tributaries.
- For a delta to form, a terrain must be close to the mouth of an ocean or a larger body of water.
- The entering stream must be large enough and have large amount of sediment.
- The river mouth must have been cut to the same level with that of the drainage basin.
- Most rivers such terrain should be at their lower course where they flow with very low velocity.
- Wave action should be minimal along such coasts.
These processes takes several thousands of years if not millions.
