Transportation is the movement of material in the sea and along the coast by waves. The movement of material along the coast is called longshore drift.

Although longshore drift is the main process of transportation the material moves in four different ways. These are:

Traction – large pebbles and boulders are rolled along the seafloor.

Saltation – beach material is bounced along the seafloor.

Suspension – beach material is suspended and carried by the waves.

Solution – material is dissolved and carried by the water.
