Deltas

• Deltas are formed at the end of rivers (river mouth) as it flows into the sea.
• Rivers carry a lot of sediment (mud).
• The river flows into a calm sea.
• This slows the river down.
• Which makes the river drop its sediment.
• This deposited sediment builds up over years creating a delta.
• The river is forced to split up.
• The smaller rivers made by deltas are called distributaries.
• Examples of Deltas are Nile Delta, Ganges Delta.
