Study Notes
Delta Formation
- Deltas form at the mouth of a river where it enters a sea.
- They are fan-shaped landforms created by deposited material.
- River currents slow down as the river reaches the sea.
- The slowed currents cause sediment to deposit at the mouth of the river.
- Over time, the deposited sediment accumulates forming a delta.
Delta Characteristics
- The river slows down at the mouth due to silt deposits and a gentle gradient.
- The river splits into smaller streams as it moves into a gentle gradient.
- The river navigates around sand deposits that hinder its flow.
Coastlines Not Suitable for Delta Formation
- A steep seabed next to the coastline can cause deposits to be washed away.
- Coastlines with a large tidal range do not allow for material accumulation.
- Strong ocean currents prevent material accumulation and delta formation.
