* Beach Formation: The most obvious example! Waves carry sand and sediment towards the shore, where they are deposited to form beaches.
* Spit Formation: When longshore currents (currents running parallel to the shore) carry sediment along the coast, they can deposit it in a long, narrow strip of land that extends out into the water. This is called a spit.
* Tombolo Formation: Similar to a spit, a tombolo is a depositional landform that connects an island to the mainland. This happens when sediment is deposited between the island and the mainland.
* Barrier Island Formation: These are long, narrow islands of sand that run parallel to the mainland coast. They are formed by the deposition of sand by waves and currents.
* Delta Formation: Rivers carry sediment downstream and deposit it at their mouths, creating a fan-shaped landform called a delta.
* Lagoon Formation: When a barrier island forms, it can trap water behind it, creating a lagoon. These lagoons can be filled with sediment over time.
Key Concept:
Deposition in shoreline processes is driven by the energy of waves and currents. These forces slow down as they approach the shore, causing them to lose energy and deposit the sediment they were carrying.
