Key Points
- Delta Definition: A delta is a landform that forms at the mouth of a river, where the river meets a body of water such as an ocean, sea, or lake.
- Formation Process:
- Sediment Deposition: When a river flows into standing water, the velocity of the river decreases.
- As a result, the river deposits the sediments (sand, silt, clay) it has been carrying.
- These sediments accumulate and form a triangular or fan-shaped landform.
- Common Features:
- Deltas are characterized by multiple channels, which are called distributaries, spreading out from the main river.
- They often create fertile soil, making them important for agriculture.
- Famous Examples:
- Ganges Delta (India and Bangladesh)
- Nile Delta (Egypt)
- Mississippi Delta (USA)
