What causes shoreline deposition?

Back

Shoreline deposition occurs when sediments, soil, or rocks are added to a landform or landmass, often as a result of wave action and currents.

What is a delta?

Back

A delta is a landform that forms at the mouth of a river where it meets a body of water, created by the deposition of sediment carried by the river.

What is a sea stack?

Back

A sea stack is a tall, narrow rock formation in the sea, formed by the erosion of waves on a headland.
