​

​

• Riverbanks

• Beaches​

• Lakes

• Deltas

​

​What places can you think of where deposition happens?

​

​How did all this sediment get here?​

​

​Deposition is the ​adding of sediment in an area and creates new landforms.

​

​

​

​1. Sand dunes are formed by sediments carried by the wind.

​

​Places formed by deposition​

​

​2. River deltas are formed where rivers meet oceans by sediments carried by rivers. The sediments come from erosion upriver.
